Before you start your installation, consider the following:Number of Components. You can connect two peripheral devices to a Digi Neo 2, up to four peripheral devices to a Digi Neo 4, and eight periph-eral devices to a Digi Neo 8 adapter. Up to four Digi Neo adapters may be installed in a computer.Construction of Cables. To achieve the greatest reliability over distance, cables should be:•Shielded, low capacitance, and preferably designed specifically for serial data transmission.•Grounded at both ends of the cable.•Routed away from noise sources such as generators, motors and fluorescent lights.Cable Connections. Before beginning the installation, verify that you have the appropriate Digi connector assemblies (fan-out cables or connec-tor box assemblies). Fan-out cable and connector box options aredescribed in detail in a separate Cable Usage Guide.You will also need a cable for each peripheral that you will be attach-ing to the connector assembly. The connector type that you need at either end of the peripheral cable depends on the type of Digi connec-tor assembly that you use and the connector on the peripheral.Digi connector assemblies are available with RJ-45, DB-25 or DB-9 connectors. You will need to be sure that you have cables of the cor-rect length and with the right connectors to properly attach thedevices you want to use.Additional information about the Digi Neo adapter, such as specifications and cabling details, is provided on the Digi CD which is packaged with the adapter.Step Two: Install the Neo AdapterCAUTION! To guard against damage to the adapter due to electrostaticdischarge (ESD), do not remove the adapter from its protective packag-ing until you have grounded yourself to the computer chassis (see step 4,below).1.Shut down your computer in the manner recommended for your oper-ating system.2.Unplug power from the computer.3.Remove the computer’s cover.4.Touch the computer chassis to equalize any static potential betweenyourself and the computer. This will help prevent damage to theadapter due to electrostatic discharge.5.Locate an available PCI slot in your computer and remove the slotplate.6.Remove the adapter from its protective packaging.7.Write down the serial number of the adapter in the space providedbelow.8.Insert the adapter into the slot and screw the endplate to the computerchassis. The endplate must be screwed into the computer chassis toremain in compliance with Part 15 of FCC rules.9.Replace the computer’s cover.10.Attach the peripheral interconnect cable(s) to the adapter.CAUTION: Many SCSI adapters use the same HD-68 connector type asthe Neo adapter. Do not plug SCSI devices into the Digi connector, anddo not plug Digi peripheral cables into SCSI adapters.Serial Number: ________________________Step Three: Install Peripheral CablingYou can connect modems, terminals, serial printers, or any other standardEIA-232 device to a Digi Neo adapter using a cable between the periph-eral and the Digi connector assembly.On the peripheral end of the cable, the connector you must have dependson the requirements of the peripheral. The Digi end of the cable must beequipped with the connector type that mates with the connectors on theDigi connector assemblyIn the case of the 2 port product, the cables are connected directly to theadapter’s end-plate.。

一、引言1、编写目的软件维护是软件生命周期的最后一个阶段,它处于系统投入生产性运行以后的时期中,因此不属于系统开发过程。

软件维护需要的工作量非常大,虽然在不同应用领域维护成本差别很大,但是平均说来,大型软件的维护成本高达开发成本的四倍左右。

目前国外许多软件开发组织把60%以上的人力用于维护已有的软件,而且随着软件数量增多和使用寿命延长,这个百分比还在持续上升。

软件维护就是在软件已经交付使用之后,为了改正错误或者满足新的需要而修改软件的过程。

它有如下几种性质的维护:1)改正性维护因为软件测试不可能暴露出一个大型软件系统中所有潜藏的错误,所以在使用期间,用户必然会发现程序错误,并且把他们遇到的问题报告给维护人员。

并将把诊断和改正错误的过程称为改正性维护。

2)适应性维护计算机科学技术领域的各方面都在迅速进步,需要经常地修改版本。

为了和变化了的环境适当地配合而进行的修改软件的活动称为适应性维护。

3)完善性维护在软件编写完成之后,投入实践,在使用软件的过程中,用户往往提出增加新功能或修改已有的功能的建议,这就需要进行完善性维护。

4)预防性维护分享一个苹果,各得一个苹果,分享一种思想,各得两种思想。

BBSRC DOCTORAL TRAINING GRANTSFREQUENTLY ASKED QUESTIONS1 General1.1 What is a Doctoral Training Grant?A Doctoral Training Grant (DTG) is a grant used for providing funding for postgraduate research training. DTGs are awarded through a number of competitions:•Quota Competition•Targeted Priority Studentship Competition•Industrial CASE competition•Industrial CASE Partnership CompetitionThe DTG awarded in each case will sometimes be referred to in connection with the competition it was awarded through: for example a “Quota DTG”, or a “Targeted Priority DTG”.BBSRC began using the training grant mechanism on a pilot basis from 2002 in its Quota competition, and a similar mechanism is currently used by EPSRC and MRC – in connection with an algorithmic allocation of funding. The key feature in each case it that as opposed to funding individual studentships, where the research council itself makes stipend payments to the student and fees and a research support grant to the institution, in a DTG a single grant covering all these elements is awarded to the department.1.2 What are the advantages to a department?The principal benefit to a department is the flexibility which a DTG provides in how postgraduate training is provided. The DTG is awarded on the basis of the value of a number of 4-year studentship packages, and subject to the terms and conditions of the scheme, the department has the flexibility, for example:•to offer 4 year studentships or ‘fast track’ 3 year studentships with an enhanced stipend;•start students at any point in the academic year;•draw in funding from other sources by part-funding the student from the DTG and part from another source (see below).1.3 What is the difference between a DTG and an MTG?A Masters Training Grant (MTG) is a Training Grant awarded for the purposes of supporting students on Masters courses; a DTG is awarded for the purpose of supporting students on a programme leading to a doctorate. BBSRC is awarding its Masters funding in the form of MTGs from 2007. The Terms and Conditions for MTGs and DTGs are very similar in order to simplify the administration of the grants as much as possible for research organisations. The Terms and Conditions for MTGs are written in a generic way – with the intention, in duecourse, of moving to a single set of “Training Grant” Terms and Conditions to cover both MTGs and DTGs.2 Allocation of DTG funds2.1 How are DTG funds allocated?DTG funding is allocated through the BBSRC’s studentship competitions. From 2006, all Quota studentship allocations were awarded in the form of a DTG. DTGs were also awarded through the 2006 Targeted Priority Studentship competition, and BBSRC has decided to award all new studentships in the form of Training Grants. In each case, funding will be provided in the form of a single grant to the department (paid centrally to the Institution), profiled over the duration of the DTG.2.2 I have a BBSRC DTG awarded from a previous quota competition; does this nowcome under the new terms and conditions?No. A DTG is governed by the terms and conditions under which it was issued.3 Grant Arrangements3.1 What will be the grant start date?The date is 1 October of the first academic year covered by the DTG award.3.2 What is the duration of the grant?This will be specified in the award letter. The DTG awarded through the Quota competition provides for 3 years of intakes on 4-year studentships, and so the total length of the grant is six academic years. Note that this covers seven financial years in terms of the research councils (April – March financial year). Where a DTG covers only a single intake, the duration of the DTG will accordingly be shorter.3.3 What will happen if we are awarded further studentships in future competitions?The intention is for the department to hold separate, but overlapping, DTGs, and draw on their funding simultaneously, although the department or institution will be expected to account for funds drawn from each DTG.3.4 What happens if the student’s period of support goes beyond the end of thegrant?The balance of the funding should be made from a subsequent Quota DTG award, or from another source. The DTG is cash-limited and will not be supplemented or extended for this reason.3.5 Can we fund a student who wants to start in September or earlier?In relation to the start date for a DTG, a student can be started earlier in the year, but BBSRC will not start the grant earlier. Funds will not be released early. The Quota DTG awards extend over three annual intakes, however, and so once the grant has started the department has the flexibility to begin funding a student at any time within the period covered by the DTG.3.6 What happens if we take on a veterinary student who qualifies for the higher stipend - we will be short of funds?The BBSRC will meet any shortfall that cannot be met from within the cash limit of the DTG providing it is as a result of paying a higher stipend to a veterinary graduate than would have been paid for an ordinary studentship award. This will be paid at final reconciliation of the grant.3.7 What provision is made for additional costs incurred as a result of maternity leave?A student receiving a stipend from a Research Council Training Grant is entitled to receive stipend support during periods of maternity leave in line with statutory maternity provision, and to have their studentships extended by a commensurate period.The additional costs incurred should normally be met from within the cash-limit of the Training Account (comprising all Doctoral and Masters Training Grants). For the majority of Research Organisations (ROs), which have significant concurrent Training Grants and the expectation of regular funding in the future, this should cause no difficulties and Councils would not expect or accept any additional claims. For those ROs without such flexibility (eg a very small Training Grant and no expectation of future funding), then Councils will consider requests for additional funding above the cash-limit when this can be shown to be unavoidable. The RO will need to demonstrate that it lacks flexibility within its Training Grant to meet the costs of maternity support and that it has no or other contingency funding or concurrent Training Grants on which it could draw.4 Use of the funding4.1 Can I use the funding in any way I choose?No. As with any Research Council grant, the funding is awarded subject to terms and conditions governing the use of the funding. The terms and conditions governing DTGs have now been agreed cross-Council between the three Research Councils currently using the DTG approach (BBSRC, EPSRC and MRC). These terms and conditions specify the formal ‘minimum’ conditions for the correct use of the funding, and indicate the formal limits to the flexibility which the DTG offers to a department or institution.You also need to bear in mind the purpose of the award as determined by the competition in which it was awarded. So for example, the Targeted Priority Studentship DTGs (i.e. DTGs awarded through the Targeted Priority Studentship competition) are awarded to support research training in specified priority areas, whereas the Quota DTGs give the department autonomy in determining the areas of the individual student projects within BBSRC remit.In addition, however, BBSRC expects departments and institutions to use the flexibility of DTG funding for maximum strategic effect, and to think strategically about how best to maximise the impact of BBSRC’s investment in the department. This might include using the flexibility of part-funding to gear in funding from other sources, or offering enhanced stipends to attract the strongest candidates in areas of science in which the department may have been experiencing recruitment difficulties. Several of the following FAQs provide information regarding BBSRC’s views as to good practice in this area. Subsequent BBSRC DTG competitions will seek information about the policies and strategies used by a department or institution for using its DTG funding, and ask applicants to demonstrate how strategic decisions with regard to use of funding are reached.4.2 Do I have to create only 3-year or 4-year studentships? Can I not create 3 ½ yearstudentships, for example?BBSRC considers it good practice for a department to design research studentship projects that can be reasonably be expected to be completed in either 3 years or 4 years, and that a significant proportion need to be 4 year in view of the increasingly interdisciplinary nature of bioscience research, and the need to provide students with challenging projects. Departments should seek to ensure that students finish their research within the time period agreed for the project.4.3 Why do we need to decide upfront about whether we are offering a 3 or 4 year studentship?It is important that students are given a clear statement at the beginning of their studentship of the length of funding they can expect. An institution’s offer to a candidate should contain a clear statement of the details of the studentship support being offered. And, of course, with a DTG, it is the department which decides whether to fund a 3-year or 4-year studentship, not the BBSRC. (You should also refer to Precept 9 of the QAA’s Code of Practice on Postgraduate Research Programmes regarding the offer letter, and its role in constituting a contract between the student and the institution.)Any such statement should make clear, for example, that continued receipt of the studentship is subject to satisfactory progress, as monitored through a department’s progress monitoring procedures. With 4-year studentships, some departments state clear progression requirements toward submission in the final year for continued receipt of funding. If a student completes in less than 4 years, then the department retains the funding in its DTG, of course.4.4 If we offer a 3-year studentship, can we extend the funding period later on?A: If a 3-year studentship is offered, this does not prevent a department having clear procedures for exceptionally extending a studentship later on, on a competitive basis, if the science is showing signs of dramatic new results (as mentioned in the answer to Q 4.1). If this process is used, then for fairness we would expect to see all 3-year studentships in a department eligible for extension, irrespective of funder (though BBSRC DTG funding could be used where the studentship is BBSRC funded).Normally, however, a student should be supervised, and their progress monitored, towards submission within 3 years where a 3-year studentship has been offered. The drift towards the majority of students requiring a fourth year has lead to an unfortunate practice of the ‘writing-up year’, where, in the worst cases, a student is left with no stipend in order to complete their project. The introduction of 4-year studentships is intended to end this practice; and so 3-year studentships should mean a research project which is managed to completion (i.e. submission of the thesis) in 3 years.The completion of a project within a specified time-frame is itself, of course, an essential transferable skill (see section C of the Joint Skills Statement). Departments should seek to ensure that students finish their research within the time period agreed for the projects, and we do not expect to see departments extending the period of a studentship late in the day, unless exceptionally it can demonstrate that it is seeking to reward excellence and support exciting new research developments in a student’s project, as above.4.5 If I have a Quota DTG funding an annual intake of three 4-year studentships, can I use the DTG funding to create four 3-year studentships?While BBSRC does not wish to be overly prescriptive in the use of DTG funding, the intention in providing four years of funding per studentship package is not to allow for the creation of a larger number of three-year studentships. There is now a common perception that three-year studentships are not adequate to allow students to undertake challenging projects in view of the increasingly interdisciplinary nature of bioscience research. In recognition of this, the Government’s 2004 Spending Review made increased funding available to research councils to enable them to extend the duration of their studentships.4.6 Can I part-fund a student, i.e. part from the DTG and part from another source? Yes – but there are limits to the part-funding arrangements; see the next question for details.4.7 Is there a minimum limit to the contribution which must be made from the DTG, when a student is being part-funded from a non-Research Council source?Yes. The DTG allows for studentships to be part-funded from the DTG, and part-from another source, but in all cases of part-funding at least 50% of the total cost (where a stipend is awarded) over the lifetime of the studentship should be funded from the DTG. Where a student is being funded who is eligible for a fees-only award, 100% of the fees should be met from the DTG over the lifetime of the studentship. It is not permissible, therefore, to provide small sums of funding from the DTG to support, for example, a student funded primarily from another source. In other words, every student who is funded from the DTG must be funded according to these minimum levels, and they will count on this basis as ‘recognised’ BBSRC students. Being a recognised BBSRC student is important for the student – for example, it makes them eligible for funding to attend a UKGrad course. Numbers of recognised students will also be used, for example, in the allocation of Roberts skills training funding.4.8 Can I part-fund a studentship from the DTG of another Research Council?Yes – 50:50 funding from the DTGs of different Research Councils is permitted, and the cross-council Terms and Conditions provide further details of this. The DTG mechanism is particularly useful to facilitate studentships in interdisciplinary / cross-council areas. However, where a studentship is part-funded from the DTG of another research council, the department holding the BBSRC DTG must satisfy itself that sufficient research within the project is within BBSRC remit in order to justify the collaborative arrangement.4.9 Can I part-fund a studentship from two different DTGs, e.g. from a Quota DTG and a Targeted Priority Studentship DTG?Yes. The department may well find it useful to maximise the impact of its studentship funding by part-funding a studentship from more than one BBSRC DTG. The department will need to ensure, however, that it has suitable mechanisms in place to accurately record the funding drawn from each grant.4.10 Are there any restrictions on the areas of science in which studentships can be supported?This will depend on the competition in which the DTG was awarded. The Targeted Priority competition awards DTGs to support research training in priority areas as specified in the competition; the Industrial CASE competition makes awards on the basis of specific collaborative projects.The Quota DTG awards give considerable autonomy to the department to decide the area of science, but clear it should only be used to support postgraduate training within the BBSRC’s remit. Within this remit departments have flexibility to create studentships in the areas that they wish to support. However, departments are asked to give particular consideration to BBSRC research skill priority areas. In subsequent Quota DTG competitions, departments will be asked to provide details of the extent to which they were able to create studentships which support BBSRC’s strategic objectives.As with previous quota studentship allocations, the Quota DTG allocation may include a specified number of annual CASE awards. The department must use the funding to create CASE studentships rather than standard studentships.4.11 Is there a restriction on whether a student can take on a 4-year studentship if they have already completed more than three years of degree or postgraduate level training?No. BBSRC wishes departments to recruit the best eligible students to its studentships, having consideration of the student’s expertise and qualifications and their suitability for the particular project.4.12 Can I use funding from the DTG to give a fourth year of funding to an existing studentship?Yes, but only for BBSRC funded studentships, and provided that this is a decision taken in order to allow the student’s research to follow promising new developments. A clear assessment should be made of the likely value to the student of being able to extend their work. You should also refer to the question below on whether funding from the DTG can be used to fund a writing-up period. DTG funding cannot be used to support the fourth year of a student who has been funded for three years from a different source, as this would mean that less than 50% of the studentship is funded by BBSRC (see above).4.13 Can I use funding from the DTG to fund a writing-up period?No. If a studentship project is designed to be three years, this should be managed so as to allow for the writing up of the research within the scope of the project, similarly for a 4-year studentship. In other words, a department should not fund a student for 3 / 4 years of laboratory work and then expect the student to have to write up in their own time. The project should be designed and managed to allow for the writing up of the research within the scope of the project itself.4.14 Can we continue to fund a student from our DTG after they have submitted their thesis?Yes – but only in certain circumstances. Normally the submission of the thesis is taken to mark the end of PhD studies. However, a stipend is by definition funding provided to enable someone to undertake a period of education or training, and therefore in some circumstances it may still be possible to pay a stipend from the DTG where the student is undertaking additional relevant doctoral level education or training after the submission of their thesis. In this case, it would be important for the department to have clearly documented requirements for the further period of research training, and ensure that there is a clear end-point to the funding. BBSRC will expect to see clear added-value to funding such a period compared, for example, to using the funding to support a new student.4.15 Can I use funding from the DTG to fund Masters level training?The DTG should only be used to support Masters level training where this is an integral part of a doctoral research degree programme. The DTG allows the department flexibility to tailor a training package to a particular student, and if, as part of that training, the department wishes the student to take a course of Masters level modules, then that is allowable. However, a clear offer of a four-year doctoral programme should be made to the student.It may be particularly appropriate, for example, to include Masters level taught modules as part of the first year of a doctoral research degree programme in interdisciplinary areas. Some degree programmes, such as the ‘Integrated PhD’ or ‘New Route PhD’ may also involve taught components at Masters level. DTG funding should not be used, however, to provide stand-alone Masters studentships. Departments should also bear in mind that a fouryear submission period is expected for all students, irrespective of whether their programmes involve components at Masters level.4.16 Can I use DTG funding to provide student stipends above the research council minimum?Yes – and the DTG awards made through the Quota competition include an additional element to help with the provision of enhanced stipends in science areas in which the department or institution experiences recruitment difficulties. The Roberts Report, SET for Success (2002), recommended that stipend enhancements of £2k p.a. be awarded by institutions to assist in research priority areas experiencing recruitment difficulties. The DTG approach gives the department flexibility to provide enhanced stipends within the financial scope of the grant, in order to support its recruitment of the best students.4.17 Can I use the DTG to fund higher research support costs than under a standard research council studentship, and fund fewer studentships?Yes, it is for departments to decide the distribution of funds, taking into account the needs of the students and projects funded through the DTG, and its broader management of its postgraduate training. Funds may also be used towards the cost of travel associated with conference attendance and fieldwork both within the UK and abroad. The distribution of the funds should be tensioned against these various calls on it, and subsequent Quota DTG competitions will seek information on a department’s policy in this area.4.18 How can a department with a small account value use the funds effectively?The DTGs are awarded to departments and are intended to be flexible. Among the options are:•Collaborate with another department or university for a joint studentship;•Seek partial support from industrial or charitable sources;•Where appropriate award a higher stipend in order to attract the best student fora project.•Combine funding from the BBSRC DTG with the DTGs from other research councils to fund interdisciplinary projects.4.19 What happens when a student moves to another department or university?BBSRC expects the universities to come to an agreement about transferring resources; the DTG to either department will not be amended. Essentially, the ‘exporting’ university should make an appropriate financial transfer to the new university to cover the balance of cost of the studentship award. BBSRC expects for both institutions to place paramount importance on the interests of the student in reaching decisions about the transfer of resources.5 Selection of Students5.1 What eligibility requirements apply to students funded through DTGs?Any studentships created from the DTG are subject to the same studentship terms and conditions as the previous directly funded BBSRC studentships, and this covers also issues of student eligibility for DTG funded studentships. Existing criteria on residence and qualifications, based on the Education (Fees and Awards) Regulations 1997 and subsequent amendments, continue to apply therefore.Regarding qualifications, departments are referred to the BBSRC Studentships guide: /funding/studentships/index.html5.2 Are EU students eligible for DTG funding?The rules relating to EU nationals are complex, and it is important to remember that for all EU nationals (whether UK or non-UK), eligibility rests on residence, not nationality. You need to look at cases on an individual basis –referring to the detailed eligibility guidelines, as since 2005 the period of UK residence required for eligibility can now include periods of residence in the UK for the purpose of full-time education. Where a student is eligible for a fees only award, all the fees must be paid from the DTG.5.3 Are non-EU students eligible for DTG funding?Again, nationality or country of origin is not a criterion for eligibility. Meeting the residence requirement as set out in the Education (Fees and Awards) Regulations 1997 and subsequent amendments is the test of eligibility.5.4 How will the students know that they are funded by the BBSRC?Since students are no longer directly paid by BBSRC, there is a risk that they may not realise that they are BBSRC-funded students. It is important, therefore, that the department makes this clear to the students funded from the DTG, and one way to do this would be to use the BBSRC logo on relevant award letters or documentation. The BBSRC logo can be downloaded from:/site/download_logo.htmlWith the introduction in 2007 of a Je-S based system for the department to return student details to the BBSRC and maintain up-to-date contact details, we would hope to separately contact BBSRC-funded students with details of training and events relevant to them.6 Management of Awards6.1 What terms and conditions apply to students funded through DTGs?BBSRC will continue to issue an annual guide to studentships, BBSRC Postgraduate Studentships, containing the terms and conditions for BBSRC studentships funded from the DTG. See: /funding/studentships/index.html6.2 Can I convert a studentship to CASE?Yes. BBSRC wishes to encourage industrial collaboration, but this need not require formal “conversion” of a studentship to CASE. Departments should feel free to seek collaboration on DTG funded projects with industrial partners. Where relevant, this may also include financial contributions and time spent in industry by students.CASE (Collaborative Awards in Science and Engineering) are a type of doctoral studentship designed to incorporate an element of industrially related training to broaden experience. To use this term, the research project undertaken by the student should be agreed between the academic department and the cooperating body, and the student supervised by staff from both the academic and industrial partners. CASE awards also attract additional payments from the cooperating body to both the student and the department. To be counted as a CASE award, the studentship should meet the terms and conditions for such awards as given in the BBSRC’s studentship guide, BBSRC Postgraduate Studentships.6.3 Can part-time students be supported?Yes. Part-time arrangements may be particularly suitable for those returning from a career break or who have domestic responsibilities that preclude full-time training.Departments and students should be realistic, however, about such arrangements. It is expected that the period of study will reflect the percentage of time spent pursuing doctoral studies, and a minimum of half-time study may be appropriate (requiring an expected period of study of up to six – eight years). Supervisors will wish to ensure that the project will be able to keep up with the new research developments that are likely to occur over such an extended period of study.6.4 Can we replace students who leave early?Yes, if you have sufficient funds, and, if necessary, you can guarantee any funding required beyond the period of the current DTG from another source (if the period of support extends beyond the current DTG, you cannot be certain that your department will win a subsequent DTG award). Students who leave within the first year will not be counted against the department’s four year submission rates, but no replacement funding will be provided. If a student leaves after 12 months, BBSRC will include that student in post-award surveys on thesis submissions.7 Financial Arrangements7.1 What are the national minimum stipend rates?The minimum stipend for 2008/09 is £12,940 p.a. (outside London) and stipends for further years will be announced well in advance of the start date to allow for advertisement. Students eligible for a stipend must be in receipt of at least the research council minimum for the academic year in question, including where appropriate the current London supplement.7.2 Are increases to the stipend levels included in the grant?Yes. Increases in line with inflation are included in the grant.7.3 Can funds not committed in the first year be carried forward to a later year?Yes. They can be used at any time during the grant. Any unspent funds remaining at the end of the DTG will not be paid when the Final Expenditure Statement is reconciled. They cannot be transferred.8 Monitoring and Information8.1 What information will the BBSRC be seeking on students funded from the DTG?The terms and conditions of the DTG confirm the requirement for student and project information. It is very important for BBSRC to have information on the students (and their research) which are being supported with BBSRC funding. All Research Councils are now moving to use Je-S based electronic systems for the return of student information. BBSRC will require the return of information on the students funded from a DTG through the Je-S Student / Researcher Data portal. An outline of the information that will be required includes:•student and project details as provided on the standard nomination form•duration of studentships awarded (3 or 4 years)•start date of awards•stipends awarded•details of CASE partners and levels of contributions•breakdown of funds within the account into• stipends• fees•research training support grants8.2 When will the BBSRC be seeking student/account information from universities?Details of the students funded from a DTG should be returned to BBSRC within one month of the student starting. Annual surveys of PhD submission and completion rates (currently carried out in January) will continue. BBSRC receives first-destination data on the employment of students once they have been awarded their degrees from the HESA survey of Destinations of Leavers from Higher Education (DLHE). BBSRC would ask that departments make students aware of the importance of completing the HESA questionnaire which they will receive in due course. This information is vital for BBSRC to be able to report on the impact of its funding.。

2.1.1
选择测试系统要以完成的测试业务为依据。如Table 2-1所示:
主流测试系统如TEMS, NEMO以及我司Probe1.5版本都能够很好的同时支持CS业务和PS业务中的各种测试项,而且添加相关硬件和软件模块后能够满足MOS测试的需求;这类测试平台能够满足大多数的DT测试需求。
如果局方已经提供相应服务器,建议最好选用此服务器作为目标服务器。
如果局方没有提供,则建议现场询问本地工程师或局方人员,选用客户推荐的性能较稳定的服务器。
如果当地无法提供类似服务器,那只能选择国际上比较知名的网站服务器,能够保证TCP层的带宽不受限制。
最好有多个服务器可供下载,如果某次测试中发现性能不佳,更换服务器后重新测试,比对测试结果,排除服务器不稳定因素导致的测试性能不佳。

3.例程:
/*------------------------------------------------*/
/* 可以在 PC 机上运行的 TjpgDec 模块快速评估测试例程*/
/*------------------------------------------------*/
#include <stdio.h>
#include <string.h>
#include "tjpgd.h"
//用户自定义的解码工作中使用的应用信息的结构体(在 MCU 的使用中不需要此结构体)
typedef struct {
FILE *fp;
/*指向输入文件的指针(JPEG 文件)*/
BYTE *fbuf; /*指向输出缓冲区的指针*/
使用步骤:
1. 初始化输入的数据流(例如:打开一个图片文件)。
2. 分配 JPEG 解压缩对象和工作区。 3. 调用函数 jd_prepare() ,用于分析 JPEG 图片的信息,并为接下来的解码做好准备。 4. 根据 JPEG 图片信息分析得到的数据,对输出设备进行初始化 。 5. 调用函数 jd_decomp() ,对 JPEG 图片进行解码。
TjpgDec 技术手册 -------R0.01b 版
前言 相信大家对 FATFS 文件系统都不陌生了,2012 年 FATFS 的作者推出了 JPG/JPEG 图 片的解码函数库 TJpgDec 的 R0.01b 版,使用方法和 FATFS 文件系统的使用一样,仅仅 调用 2 个简单的库函数就能完成对 JPG/JPEG 图片的解码,而且输出的数据格式为 RGB888 或 RGB565。 本文档是根据 ChaN 的专用网页提供的英文版技术手册翻译而来,因个人水平有限 以及时间仓促,错误之处在所难免。本文档原始版权归 TJpgDec 的作者所有,本人只是 做了一下翻译的工作,把这篇文档献给所有嵌入式开发人员,希望能够帮到你们。
易于使用的主模式操作方式。 完全可重入的架构。 非常小的内存占用:
o RAM 仅占用 3KB,而不受图片大小的影响。 o ROM 占用 3.5-8.5KB,主要用于存储代码和 const
常量。 输出格式:
o 输出图片比例: 1/1, 1/2, 1/4 ,1/8 可选 o 输出像素格式: RGB888/RGB565(可预设)

UINT out_func (JDEC* jd, void* bitmap, JRECT* rect)
devid.fbuf = malloc(3 * jdec.width * jdec.height); /* 为输出缓冲区分配空间 (使用 RGB888 格式) */ devid.wfbuf = jdec.width;
res = jd_decomp(&jdec, out_func, 0); /* 开始解码,图像输出比例为 1/1 */ if (res == JDR_OK)

三.应用程序接口: 共有 2 个应用程序接口函数,用于分析和解码 JPEG 图片(译者注:移植 TJpgDec 时需要在主程序中调 用这两个库函数)
jd_prepare –为解码一个 JPEG 图片做准备 jd_decomp –解码 JPEG 图片
四.I/O 接口函数:
TJpgDec 需要用户自定义 2 个 I/O 接口函数,用于输入 JPEG 数据和输出解码后得到的像素数据。
IODEV devid;
/* 用户自定义的应用信息结构体 ,包含待打开的文件以及输出缓冲区的指针等*/
/* 打开一个 JPEG 文件 */ if (argc < 2) return -1; devid.fp = fopen(argv[1], "rb");//打开待输入的文件 if (!devid.fp) return -1;
Input funciotn - 从输入的数据流中读取 JPEG 的数据 Output function – 把解码后得到的像素数据发送到输出设备
五.备注说明:
TJpgDec 应用模块是一款可用于教育和研发的开源软件。你完全可以根据自己的项目需要或者商 业产品的需要,自由更改本软件,而不用担负任何个人责任。
嵌入式奋勇前进 2013-10-20
一.前言: TJpgDec 是一款为小型嵌入式系统服务的高效且完善的 JPEG 图片解码模块。它占用内存极少,因
此可以移植入像 AVR,8051,PIC,Z80,Cortex-M0 等等小型单片机中。 二.特点:
库函数是按照 ANSI-C 规范编写的,所以应用平台不受 约束。
/* 为 TjpgDec 分配一个解码工作区 */ work = malloc(3100);
/* 做好准备解码的工作 */ res = jd_prepare(&jdec, in_func, work, 3100, &devid);
if (res == JDR_OK) {
/* 准备解码. 此处的图片信息是有效的. jdec.width:图片的宽度, jdec.height 图片的高度 */ printf("Image dimensions: %u by %u. %u bytes used.\n", jdec.width, jdec.height, 3100 - jdec.sz_pool);
/* 从数据输入流中删除数据*/
return fseek(dev->fp, nbyte, SEEK_CUR) ? 0 : nbyte;//对文件中的数据进行重新定位,相当于删除相应的数据
}
}
