基于AVR单片机温度控制的硬件电路设计研究

为了控制某温度场的变化,本文设计了基于AVR单片机ATmega16的硬件电路,选用半导体温度传感器DS18B20进行温度的采集,并由LED数码管显示,键盘输入预设值的调整,通过继电器输出完成加热开关占空比的调控,实现该温度场的恒温控制。     

“硬件产品+软件服务”视角下的产品定价策略研究——以iOS和Android为例

智能手机通过"硬件产品+软件服务"的方式，影响着越来越多人的生活，如何处理硬件与软件间的关系，已经成为行业亟需妥善处理的问题。通过分析iOS和Android生态系统中，硬件厂商与第三方软件提供商间的关系以及用户对硬件和软件的选择行为，从竞争的角度构建硬件厂商的产品价格优化决策模型，并结合iOS和Android的现实情况和行业发展趋势对模型进行拓展。模型分析结果揭示了硬件免费的基本逻辑：尽管iOS较高的应用内购买服务费会提高用户的软件服务购买成本，使部分用户流失到Android平台，从而降低iOS在软件服务领域的提成收益，在软件服务收益降低的同时，较高的应用内购买服务费会使苹果公司的硬件销售量大幅增加，从而在总体上使苹果公司的收益增加。而Android平台的硬件厂商想要实现对iOS平台硬件产品的逆袭，除了倡导"硬件免费"外，在未来还需要在品牌价值方面有大幅度的超越。     

Optimal Pricing and Rebate Strategies in a Two‐Level Supply Chain

For many product categories, manufacturers and retailers often offer rebates to stimulate sales. Due to certain adverse effects, however, some manufacturers and retailers are contemplating the elimination of their rebate programs. This paper sheds light on the debate about the value of rebate programs by presenting a model for evaluating the conditions under which a firm should offer rebates in a competitive environment. Specifically, we consider a two‐level supply chain comprising one manufacturer and one retailer. Each firm makes three decisions: the regular (wholesale or retail) price, whether or not to offer rebates, and the rebate value should the firm decide to launch a rebate program. We determine the equilibrium of a vertical competition game between the manufacturer (leader) and the retailer (follower), and we provide insights about how competition affects the conditions under which a firm should offer rebates in equilibrium.     

界面管理任务对核电厂操纵员的认知行为影响分析

为了识别界面管理任务对核电厂操纵员的认知行为的影响,首先对核电厂数字化主控室人机界面特征进行分析,并识别操纵员的主要认知行为特征,然后分别从监视检测、状态评估、计划响应、计划执行4种主要的认知行为进行分析,识别界面管理任务对其的影响。结果显示,界面管理任务对认知行为产生的不利影响主要表现为操纵员的认知负荷和操作负荷的增加。针对上述的不利影响,提出了相应的人因失误预防对策。     

农村幼儿园体育活动硬件设施现状调查——以甘肃省积石山县为例

幼儿园体育硬件设施与体育活动的开展密切相关。通过文献资料、调查问卷、访谈等研究方法,调查甘肃省积石山县农村幼儿园体育活动硬件设施的现状,发现积石山县农村幼儿园存在户外场地不足、室内场地缺乏;场地材质安全系数低;体育器材数量不足、种类欠缺;自制器材建设较落后的问题。建议扩大户外场地面积,拓展室内场地功能;优化场地材质,增加保护性地面;扩大器材种类,增加器材数量;鼓励自制器材,培养幼儿创新能力;多方式筹措资金,加大经济投入。     

进程通信机构在UNIX V7中的实现

对于操作系统来说,进程间通信(IPC)是它必不可少的功能。本文首先分析了UNIX V7中现有的IPC功能,指出了其不足之处,作为实现IPC的一种尝试,我们在UNIX第七版内核中实现了基于Socket的进程通信机构SIPC(SocketIPC),SIPC完全克服了原UNIX V7中进程通信机构的局限性。     

Information Technology Clusters in India

The Indian information technology (IT) industry is deeply entrenched in the key metros of India, giving rise to seven large IT clusters. The country's tier I cities Bangalore, Delhi, Chennai, Hyderabad, Pune, Mumbai, and Kolkata have all emerged as significant IT hubs. The seven IT clusters are different in their history, economic weight, activity base, anchor companies, business models, government role, and other driving forces. However, even as these cities are attracting IT investments and creating employment for thousands of citizens, the drawbacks of overstressed infrastructure, escalating real estate costs, and shortage of skilled IT professionals represent challenges for IT organizations. The paper substantiates the inevitability of the hardware and software sectors linked development at this stage. It is the first attempt to study the IT industry in India through the prism of the countrywise cluster development and combination of IT sectors – hardware design and manufacturing, IT services, software and research and development, and IT-enabled services for business process offshoring.      

The urban-rural interface: Urbanization and tropical forest cover change

A considerable body of empirical and theoretical literature on the causes of tropical deforestation has emerged over the last twenty years. Recognizing that small-farmers in the Amazon Basin are a key agent in the process of primary forest conversion, a growing genre of studies at the household level have attempted to quantify the influence of various factors on small-farmer land-use decisions. Many of these studies have acknowledged the seeming importance of urban centers as hubs of propulsive activity and information, yet none have comprehensively captured the urbanization factor in rural land use decisions. I argue that this methodological shortcoming in empirical work to-date reflects an inadequate conceptualization of the range of urban-based networks and their inter-relationships. In an effort to overcome this roadblock to further empirical discovery, I review several leading schools of thought that might be pressed into service in developing a framework for interpreting the urban influences on rural landscapes. I call this construct the Urban-Rural Interface. This is not a complete theoretical model or a unique methodology, but rather an initial effort to develop a general framework from which more sophisticated formulations might proceed.
