Mid-Course Guidance Law for Long Range Multi-Purpose Missiles

A useful mid course guidance law for long range multi purpose missiles is proposed. The law consists of two parts. One is used in the horizontal guidance plane, and the other in the vertical guidance plane. The mid course is combined with variable structure proportional navigation in the homing phase. Simulation results show that the proposed guidance law can meet the demands for starting up the homing phase and so the handing over between mid course guidance and terminal guidance can be carried out successfully.

Empowering Rice Farmers in Nueva Ecija, Philippines: A Strategic Approach to Boosting Income through Special Purpose Rice Production

Low income is the main problem of millions of farmers who are cultivating 4.81 million hectares in the Philippines. This problem is attributed to challenges specifically low yield, low quality of produce, and significant post-harvest losses, particularly in a resource-scarce setting. This study aimed to help increase the farmers’ income in selected towns of Nueva Ecija through the promotion and use of special purpose rice production technology. Twenty (20) farmer-cooperators in three towns of Nueva Ecija were selected to demonstrate the production technology covering a total area of 4.75 hectares during the dry season, and 3.3 hectares during the wet season, both in 2023. Extension modalities such as training, techno-demo establishment, information material and technical assistance provision, and market linkage were undertaken to enhance their knowledge, attitude, and skills on special rice production and enterprise. The study utilized the descriptive quantitative method wherein the data were gathered through surveys, specifically personal interviews. Results showed that 70% of the farmer-cooperators were male and 60% were living below the poverty threshold. The farmers were 53 years old on average and engaged in farming as their primary source of income. The average yield of special purpose rice particularly the CLS-2 variety was higher (6.46 MT/ha and 6.22 MT/ha during dry and wet seasons, respectively) than that of inbred or non-special rice. The income per hectare from special purpose rice production per hectare was Php 75,420.00, which is higher than that of regular rice at Php 29,389.00, giving a higher benefit of Php 46,031.00. The technology adopters and area planted increased (from 6 to 9 and from 1.4 hectares to 2.75 hectares, respectively) in Licab, Nueva Ecija. The opposite was true in Sto. Domingo and Guimba, Nueva Ecija where farmers were discouraged by the marketing issues that arose.

Water Quality Assessment of the Owena Multi-Purpose Dam, Ondo State, Southwestern Nigeria

Composite water samples taken from Owena Multi-purpose Dam in six sampling campaigns covering the wet and dry seasons were analyzed for physico-chemical and microbial characteristics using standard methods for the examination of water and wastewater jointly published by the American Public Health Association, American Water Works Association and Water Pollution Control Federation. Results showed significant (p < 0.05) seasonal variations in most measured parameters with few showing significant spatial variation. The characteristics of the water from the dam lake revealed an acceptable quality for most measured parameters with low chemical pollutants burden when compared with drinking water standards and water quality for aquaculture. However, high values of turbidity, colour, iron, manganese and microbial load were recorded compared with drinking water standards, which call for proper treatment of the water before distribution for public consumption.

Trip Purposes of Automobile Users Inference Using Multi-day Traffic Monitoring Data

Determining trip purpose is an important link to explore travel rules. In this paper,we takea utomobile users in urban areas as the research object,combine unsupervised learning and supervised learningm ethods to analyze their travel characteristics,and focus on the classification and prediction of automobileu sers’trip purposes. However,previous studies on trip purposes mainly focused on questionnaires and GPSd ata,which cannot well reflect the characteristics of automobile travel. In order to avoid the multi-dayb ehavior variability and unobservable heterogeneity of individual characteristics ignored in traditional traffic questionnaires,traffic monitoring data from the Northern District of Qingdao are used,and the K-meansc lustering method is applied to estimate the trip purposes of automobile users. Then,Adaptive Boosting(AdaBoost)and Random Forest(RF)methods are used to classify and predict trip purposes. Finally,ther esult shows:(1)the purpose of automobile users can be mainly divided into four clusters,which includeC ommuting trips,Flexible life demand travel in daytime,Evening entertainment and leisure shopping,andT axi-based trips for the first three types of purposes,respectively;(2)the Random Forest method performss ignificantly better than AdaBoost in trip purpose prediction for higher accuracy;(3)the average predictiona ccuracy of Random Forest under hyper-parameters optimization reaches96.25%,which proves the feasibilitya nd rationality of the above clustering results.

Purpose融合:基于风险purpose的隐私查询访问控制

基于purpose的查询技术是关系数据库对隐私数据访问控制的基础,目前大多数研究都仅仅关注在独立隐私保护数据库环境下,如何建立有效的基于purpose的隐私数据访问控制模型.但随着分布应用整合和数据共享需求的日益增长,如何合并独立应用下基于purpose访问控制模型的问题就应运而生.为解决这一问题,文章提出了多应用系统集成环境下基于融合purpose的隐私数据访问控制实现机制.文章首先分析了由于合并独立purpose模型而引起的潜在隐私数据查询泄漏,提出了合并后的purpose树是一棵隐私泄漏风险树,并给出了树结点隐私风险度的计算模型.其次,将隐私泄漏风险树分解成一棵所有结点风险度为0的风险平衡树以及一组由风险度不为0的结点组成的风险路径.这样,一个查询可被改写为先对风险平衡purpose树的查询,再对风险路径查询,以此达到隐私泄漏风险最小的安全查询结果.文章给出了3组实验的结果:(1)对于同一用户同一查询,在不同purpose模型下的查询时间比较.文章提出的模型并没有在查询时间上带来更大的开销.(2)对RPPAAC模型防止隐私数据泄漏的有效性验证.文中的模型可降低由应用整合引起访问控制机制不平衡所带来的隐私数据泄漏风险.(3)不同情况下purpose融合的执行时间比较.文章与相关研究的不同之处是将purpose作为隐私数据的载体、purpose树的路径作为隐私数据的传递通道,引入了显性隐私度和隐性隐私度的计算模型,评估基于一个purpose查询可能带来的隐私泄漏风险,进而提出了多应用系统集成环境下基于融合purpose的隐私数据访问控制实现机制.

基于Purpose的隐私数据访问控制模型

随着各行业对隐私数据访问指导规范的颁布,如HIPAA、OECD,隐私数据的访问控制逐渐成为隐私数据管理领域的一个研究热点。关系数据库中基于角色和视图的访问控制机制实现了对用户访问权限的控制,但是不能解决面向隐私的访问控制问题。隐私数据描述的关键元素是具有层次结构的data purpose,而已有的基于data purpose的访问控制模型具有隐私策略冗余和没有考虑返回结果最大化的缺点。提出了一种新的基于purpose的隐私数据访问控制机制(R-PAACEE),通过对data purpose的概念分层,用二元组数据结构描述data purpose的层次数据模式,减少了隐私策略冗余,进而提出分离隐私与非隐私属性的查询重写算法,实现了查询返回结果的最大化。实验结果表明,针对隐私数据的查询访问,已加载R-PAACEE的数据库管理系统能够获得较好的查询效率。

Effect of Cerium on Mechanical Performance and Electrical Conductivity of Aluminum Rod for Electrical Purpose

The effect of rare earth element Ce on mechanical performance and electrical conductivity of aluminum rod for electrical purpose were studied under industrial production condition. Using optical microscope, SEM, TEM, EDS and X-ray diffractometer, the microstructure and phase composition of aluminum rod were measured and analyzed. The results indicate that the content of rare earth element Ce is between 0.05% -0.16% in the aluminum rod for electrical purpose. Its tensile strength is enhanced to some extent. The research also discovers that the tensile strength is enhanced remarkably with impurity element Si content increases. Because influence of Si is big to the conductivity, the Si content should be controlled continuously strictly in the aluminum for electrical purpose. Adding rare earth element Ce reduces the solid solubility of Si in the aluminum matrix, and the negative effect of Si on the aluminum conductor reduces effectively. So the limit of in Si content in aluminum rod for electrical purpose can be relaxed moderately.

Firmness of purpose in life significantly influences emotional state and autonomic nervous activity

The present study was performed to clarify the influence of having a firm purpose in life (PIL) on psychological and physical stresses. Participants were 59 subjects (19 males and 40 fe- males) with a mean age of 30.9 years (standard deviation, 12.1;range, 18 - 68 years). We used a mental arithmetic (MA) test as a goaloriented stressor;the test was supposed to be finished before a time limit expired without using pencil and paper. We used a PIL test to assess the intensity of personal meaning in one’s life, an interest in mental arithmetic test (IMAT) to assess the intensity of interest in the MA test, and an anxiety inventory (AI) to assess the anxiety level of before and during the MA test. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and nose tip temperature (NTT) were recorded before and after MA. We used logistic regression modeling to estimate the odds ratio (OR) of independent variables of age, sex, PIL test score, AI score, HR, SBP, DBP, and NTT before the MA test. Multivariate-adjusted models showed that PIL test scores prior to the MA test significantly predicted the observed changes in AI score and HR. Other variables were not significant predictors. In conclusion, we found that a firm PIL decreased anxiety under psychological stress as measured with the MA test, even with objective evaluation by others. Having a firm PIL also lowered the response of the sympathetic nervous system to psych0logical stress.
