“Instruction-Category” Approach of Test Suite Construction for Oven Embedded System

Being different from testing for popular GUI software, the “instruction-category” approach is proposed for testing embedded system. This approach is constructed by three steps including refining items, drawing instruction-brief and instruction-category, and constructing test suite. Consequently, this approach is adopted to test oven embedded system, and detail process is deeply discussed. As a result, the factual result indicates that the “instruction-category” approach can be effectively applied in embedded system testing as a black-box method for conformity testing.

基于Fluent与GT-SUITE联合仿真的FSC赛车进气系统设计与优化

针对2023年中国大学生方程式汽车大赛赛规中加装限流阀以限制发动机功率的要求,通过Fluent与GT-SUITE的联合仿真,对进气系统进行设计与优化,从而减小进气系统的阻力损失,提升发动机的动力性。利用Fluent对限流阀进行计算流体力学(CFD)仿真分析,得到限流阀最优结构参数为过渡圆角r=40 mm、渐缩角α=14°、渐扩角β=6°。采用GT-SUITE建立发动机数值仿真模型,分析进气系统其他结构参数对发动机充量系数和扭矩的影响,进行合理的结构优化,得到进气管长度l=145 mm、稳压腔容积V=3.5 L。仿真结果表明:限流阀的阻力损失减小了2.48%,在低、中转速区间,发动机的充量系数和转矩得到了提升,其中在5000 r/min时充量系数增大了2.61%。

Bernard Suits的游戏哲学及相关争论

Bernard Suits(伯纳德·苏茨)是美国著名的体育哲学家,一生致力于探究玩耍、游戏、运动等概念及其关系,为游戏哲学的发展做出了巨大贡献。Suits的游戏哲学主要包括4个方面,即玩耍、玩游戏、玩游戏与乌托邦,以及玩耍、游戏与运动的关系。玩耍方面的争论集中在玩耍是否涉及资源重新分配,自有目的是否具有客观性;玩游戏方面的争论集中在游戏是否可定义,定义是否过宽或过窄,定义的内容是否准确;玩游戏与乌托邦方面的争论集中在乌托邦是否完美,游戏乌托邦是否存在;玩耍、游戏和运动关系方面的争论集中在三者是否存在交叉关系,分类依据是否出现类型错误,Suits的游戏哲学有助于审视当下的体育现象和问题。

Impressions of Hazmat Suits Based on Color

Background: Commonly, skin and clothing surface contamination screening (radiation survey) is performed for residents of an area to confirm the levels of residual contamination after nuclear power disasters. Examiners for such a screening often wear white radiation hazmat suits. However, it has been reported that examinees tend to feel tension or anxiety. In this study, we focus on the color of the radiation hazmat suit as one measure to reduce residents’ tension or anxiety. This study aims to determine the common conceptions of radiation hazmat suits based on color. Methods: An anonymous self-administered questionnaire survey was conducted with a total of 262 participants consisting of nursing students, administrative staff of a university, general citizens, and mothers raising their children in the Tohoku region in Japan. The common impressions of radiation hazmat suits, which are typically white, were measured using the Multiple Affective States Scale. This scale can measure the affective state brought about by clothing. The color of white (W) was defined as a standard color commonly used for hazmat suits;in order to determine the common impressions of radiation hazmat suits based on color, the following additional colors were shown to the participants: salmon pink (P), ivory (I), and light green (G). Results: There were no sex differences regarding common impressions of radiation hazmat suits. For white radiation hazmat suits, a high score reflecting the characteristic of “capable” was obtained, while the scores for “cheerful” and “calm” were low, and those for “depressed” and “tense” were high. The colors that showed the highest score for “calm” as a positive affirmative state were I and P. W and P reflected a high “ashamed” score, and the “tense” score for G was higher for the participants in their 20s than for those in their 30s and older. Conclusions: Results show that the color of hazmat suits provokes far greater feelings of anxiety and tension on participants than previously thought. Radiation hazmat suits may be further improved based on the results of this study.

Incorporation of Cutting for Customized Suits

The theoretical male body size and its distribution plan are studied in consideration with the nation standard and the information provided by several garment companies. Through nine times tries of marking two suits with the CAD marking module, the fabric length and rates are derived. The formulas of the marking fabric length, the length total, and the girth total are obtained by using SPSS software. Moreover, by comparing the two incorporation methods of cutting in which one in the arithmetic sequence and the other in the geometric sequence, it is found that the one in the arithmetic sequence is better than the one in the geometric sequence.

Adaptability analysis and optimization of log suite for uncased wellbores of shale gas reservoirs:A case study of Sichuan Basin,China

Significant progress has been made in the exploration and development of unconventional gas resources in China since the beginning of the 21st century.With a rapid increase in yield,the exploration and development of shale gas have been upgraded to a level of national strategy.Logging is one of the core technologies in gas exploration and development.However,logging technologies face the challenges of complex geological conditions and well casing environment,high temperature,high pressure,and strong heterogeneity.Despite the rich experience accumulated,unified understanding and implementation specifications are yet to be established for shale gas well logging.Given the analysis and comparison of the effectiveness and adaptability of logging technologies at different stages of shale gas exploration and development for the Sichuan Basin,this study optimizes the log suite to meet the demand for highefficiency exploration and development of shale gas.According to the adaptability analysis of shale gas log suite,the mandatory logging items of exploratory wells should include caliper log(CAL),natural gamma ray spectrometry(NGS)log,spontaneous potential(SP)log,directional survey,borehole compensated sonic log,litho-density log(LDL),compensated neutron log(CNL),dual laterologmicrospherically focused log/dual induction-laterolog log/array induction log,temperature log,elemental capture spectroscopy(ECS)log,formation microimager(FMI)log,and array sonic log.The log suite of appraisal wells is almost the same as that for exploratory wells,excluding the ECS log and microresistivity scanning imaging.Meanwhile,for the logging of horizontal/highly-deviated holes,the log suite of vertical wells should be referred to according to specific well conditions.

松辽盆地海力锦铀矿床黄铁矿微量元素、硫同位素特征及其对成矿流体性质的指示

海力锦铀矿床控矿灰色砂岩垂向上具有“两红夹一灰”特征,铀矿体呈多层板状,与传统的层间氧化带砂岩型铀矿明显不同。文章通过对赋矿灰色砂岩中黄铁矿微区微量元素和硫同位素特征研究,反演海力锦铀矿床成矿流体性质及来源,主要获得了以下几点认识:(1)海力锦铀矿床含矿层黄铁矿赋存形式包括胶状、草莓状,铀矿物常与草莓状或胶状黄铁矿共伴生于有机质胞腔内或矿物粒间孔隙。(2)黄铁矿微量元素特征显示,As、Mo、Sb等亲硫性元素从核部到边部含量增高,Mo、Ni、Zn、Cu、Ba等元素与U具有较好的正相关性,这些元素在大气降水中难以沉淀和富集,往往富集于深部还原性流体中。硫同位素δ34SV-CDT值显示从核部到边部明显降低的特征,表明黄铁矿形成环境发生了较大改变,指示海力锦铀矿床成矿流体可能为深部具有一定温度的还原性流体。(3)松辽盆地西南部深部发育厚度大且面积广的富铀烃源岩,海力锦铀矿床东南部F1断裂为沟通深部富铀烃源岩和含矿层的深大断裂,据此认为海力锦铀矿床成矿流体可能来自深部还原性流体(富铀烃源岩),控矿灰色砂岩为还原性流体对原生氧化沉积建造的还原改造。

Guideline of Test Suite Construction for GUI Software Centered on Grey-Box Approach

In this paper, the test suite construction for GUI (Graphical User Interface) software may be executed centered on grey-box approach with the prior test design of window access controls for unit testing, including front-end method of white box and follow-up black box method for integration testing. Moreover, two key opinions are proposed for the test suite construction for GUI software, the first one is that the “Triple-step method” should be used for unit testing with the prior disposing of data boundary value testing of input controls, and another one is that the “Grey-box approach” should be applied in integration testing for GUI software with necessary testing preparation in the precondition. At the same time, the testing of baseline version and the incremental testing should be considered for the test case construction to coordinate with the whole evolution of software product today. Additionally, all our opinion and thought are verified and tested with a typical case of GUI software—PQMS (Product Quality Monitoring Software/System), and results indicate that these methods and specific disposing are practical and effective.

基于数量化理论Ⅰ的女西服款式感性评价

为了设计出符合消费者感性需求的服装产品,以女西服为研究对象,提出感性工学与数量化理论Ⅰ相结合的款式设计研究方案。首先通过语意差异法获取消费者对女西服样本的感性评价,利用SPSS软件对感性评分进行分析,提取感性因子,创建女西服二维感性分布空间。同时分析款式特征,归纳出女西服主要设计要素,在此基础上应用数量化理论Ⅰ,通过线性回归分析得出感性因子与设计要素之间的关联预测,并构建数学模型。经验证,该模型实测值与预测值之间拟合度较高,符合正态分布要求,模型有效可行。最后通过案例设计与验证,进一步证明该模型能够实现人的感性需求与女西服设计要素之间的有效转换,对女西服款式设计与感性评价提供一定借鉴作用。

论标准必要专利FRAND诉讼中禁诉令的谦抑性

目前禁诉令颁发所采用的“前置化”思维,导致了跨国FRAND诉讼中的禁诉令冲突。这不仅增加了当事人纠纷解决的成本,还损害了国际礼让原则,引发了国家和地区之间的对抗与摩擦。禁诉令自身的制度逻辑决定了其应均衡国际礼让原则维护与限制,兼容司法能动主义与克制主义,保持足够的谦抑性,回归应对外国法院司法干涉的被动性与补充性地位。在规则上,应基于遵循国际礼让原则,促进FRAND许可交易达成,适应各国创制FRAND政策要求的优势,确立FRAND纠纷专利登记国专属管辖规则。在方法上,应摈弃“颁发前置化”思维以及抽象道德判断,以比例原则建构分析框架,分别对本国诉讼与外国诉讼的重合度、当事人之间的利益损害、国际礼让原则的影响进行评估与分析,权衡各方利益,以此作为禁诉令颁发的依据。
