智能网联汽车体系结构与关键技术

智能网联汽车（Intelligent connected vehicles,ICV）是无人驾驶技术的核心载体,产业链长,市场巨大,吸引了国内外众多汽车厂商和信息企业都纷纷投向ICV的研发与测试,部分ICV车型已进入量产阶段,新的概念车型也陆续提出。针对新型ICV的发展现状与关键技术,从ICV智能化和网联化两个维度对ICV中涉及到的相关技术进行分析,进一步从信息处理的感知层、决策层、控制层3个层次构建了ICV发展过程中的关键技术体系结构。研究表明,车辆环境感知和通信技术技术涵盖自车状态和外部环境,短程通信技术（DSRC）、机器视觉和激光雷达技术是实现车辆环境信息采集功能完善的关键;车路协同系统涉及车—车通信、车—路通信、车—云通信,协同智能交通系统、云平台和大数据技术是车路协同技术的关键;驾驶辅助技术包括自适应巡航控制系统、车道偏离/避免系统、碰撞预警/避免系统等8个构成,这是辅助驾驶、部分自动驾驶和有条件的自动驾驶3个智能化阶段中的关键;具有自主学习、自我决策的人工智能技术和信息安全技术也是智能网联汽车的关键技术,在此基础上,还应该实现多种技术间的相互支撑与融合,克服关键技术协同障碍,才能实现ICV的市场推广与普及应用。     

Using the integrative model of behavioral prediction to understand college students’ STI testing beliefs,intentions, and behaviors

ABSTRACT

Objectives: To identify salient behavioral determinants related to STI testing among college students by testing a model based on the integrative model of behavioral (IMBP) prediction. Participants: 265 undergraduate students from a large university in the Southeastern US. Methods:Formative and survey research to test an IMBP-based model that explores the relationships between determinants and STI testing intention and behavior. Results: of path analyses supported a model in which attitudinal beliefs predicted intention and intention predicted behavior. Normative beliefs and behavioral control beliefs were not significant in the model; however, select individual normative and control beliefs were significantly correlated with intention and behavior. Conclusions: Attitudinal beliefs are the strongest predictor of STI testing intention and behavior. Future efforts to increase STI testing rates should identify and target salient attitudinal beliefs.     

用数值模拟方法研究气井产量递减

运用数值模拟软件的单井模拟器,建立了异常高压气藏气井和正常压力气藏气井产量递减的单井模型,得到了异常高压气藏气井和正常压力气藏气井的产量递减数据。根据这些产量递减数据,由两种产量递减自动拟合模型分别计算了异常高压气藏气井和正常压力气藏气井的产量递减参数、地层物性参数(k_gh、k_g/Φ)及地质储量。为了提高计算精度,采用根据拟稳态的产量递减数据(去掉不稳定的递减数据)来反求地层参数和地质储量,并根据自动拟合模型的检验标准对计算结果进行了检验。结果表明,由两种产量递减自动拟合模型计算的产量递减参数和地质储量与数值模拟的计算结果非常吻合,再次证明了这两种产量递减模型的适用性。     

基于规则的英语名词短语结构自动识别研究

名词短语是英语句子的核心组成部分,然而不同名词短语类型的结构用法及其在句子中成分的复杂性一直困扰着英语的机器识别技术。本文以人民日报语料库（1998年）为基础,探讨了基于规则的英语名词短语结构用法、搭配中心词归类算法、词性与语义搭配模式抽取算法,揭示了名词短语类型与其在句子中所作成分的关系,明显地提高了名词短语识别精度。     

Keynote 3. Living in the Valley of Death

Abstract

In 2003 alone, HIV/AIDS killed more than three million people, of which between 2.2 and 2.4 million were from Sub-Saharan Africa. This disease is having a devastating effect on the previously firm foundations of intergenerational relationships in affected countries. For many nations in Africa, Asia and South America, life has become a mirage, a paradox in which almost everything is overshadowed by the pangs of death. Poverty, HIV/AIDS and, surprisingly, compassion are the combined common causes of death. Consequently, social, ecological, economic, political and educational systems are almost entirely dislocated. Traditions demand that the young ones should outlive their elders. So there is a deliberate effort on the part of the elderly to embrace death in attempting to be compassionate. This paper is an attempt to explore this scenario with the aim of articulating the linkage between poverty and HIV/AIDS, and proposing ways of reducing their impact through intergenerational programming.     

Where We Are Now with Intergenerational Developments

ABSTRACT

Intergenerational programs are beginning to burgeon in England. They are relatively recent in their development. The systemic absence of connectiveness between policy developments and services relating to older people and those relating to children and young people is identified. The key strategic players are described. Questions about future developments and research are discussed.     

EAP's:

By the end of 1990, 156,024 cases of AIDS had been reported throughout the United States (CDC, 1991). Perhaps even more devastating is that 100,813 individuals, 64.6% of the reported AIDS cases have died (CDC, 1991). The AIDS crisis has now found its way into most segments of our society. Women are now the fastest growing category of people with acquired immune deficiency syndrome (Stuntzner-Gibson, 1991). HIV disease is increasingly being identified with poor people, intravenous drug users and ethnic minorities (Honey, 1988; Macks, 1988).     

Gay,Lesbian, Bisexual,and Transgender (GLBT) Elders

Abstract

Current gay, lesbian, bisexual, and transgender (GLBT) individuals age 65 years and older grew up before the Gay Rights movement. They have learned over many years to hide their identities in order to avoid discrimination and ridicule. Unfortunately, this secrecy has led to the near invisibility of the elder GLBT population and to poor health and service access. This paper reviews what we know about GLBT elders, describes some of the unique strengths they bring to the aging process, and outlines some of the challenges they face. Micro, mezzo, and macro practice implications are suggested.     

The Passing Scene

Into the Lion's Den:

The need to "couple," to have that special person with whom we share not only sexual intimacy but a past, present, and future, is not limited to the "straight" world. Raised by heterosexual parents, gays (male homosexuals) desire that same type of intimacy. Given that intimate relationships provide a very necessary function for the larger community of heterosexuals, those relationships should provide the same function for gays. This paper examines the differences and similarities between long-term gay and heterosexual intimate relationships, and the support each of those types of relationships receives from the community in which they exist.
