Mobile wireless computing devices such as cellphones, pagers, personal digital assistants, pocket PCs, and tablet computers are all potential platforms for participating in small group, wireless, many-to-many distributed applications. The networking technology needed to support such applications is readily available. However, almost all existing middleware infrastructure for distributed applica...

In the current web infrastructure, access to content is achieved from a variety of terminals such as desktop PCs, smart phones, set top boxes and personal digital assistants (PDAs). The different capabilities of these terminals led to the development of a variety of parallel webs each one accommodating a particular device feature. This situation poses a serious problem to web designers and main...

There has been steady growth in the global population of elderly people, challenging researchers in the HCI community to design technologies to help older people remain independent and preserve their quality of life. Some researchers have created assistive technology solutions using Personal Digital Assistants (PDAs). Critics question whether older people can use PDAs because of age related dif...

Improving metabolic control reduces microand macrovascular complications of diabetes. However, intensive insulin therapy increases severe hypoglycemia more than threefold (1–3). Continuous glucose monitoring (CGM) is being introduced into routine clinical care despite a lack of reimbursement. Registration studies for the Food and Drug Administration (FDA) documented that subjects using real-tim...

The advent of portable laptop computers, palmtops, and personal digital assistants with integrated communication capabilities facilitates mobile computing. With an increasing amount of audio and video being sent over public, packet-switched networks, the ability to provide quality of service (QoS) guarantees may be more important in today's networks. Therefore, supporting a high Quality of Serv...

Everyday appliances, including telephones, ovens, and home stereos, increasingly contain embedded computers to provide greater functionality. Unfortunately, as these appliances become more complex, their interfaces are becoming harder to use. At the same time, more people than ever are carrying computerized devices that can communicate, such as cellular telephones, personal digital assistants, ...

Evolutionary multicriteria optimization has traditionally concentrated on problems comprising 2 or 3 objectives. While engineering design problems can often be conveniently formulated as multiobjective optimization problems, these often comprise a relatively large number of objectives. Such problems pose new challenges for algorithm design, visualisation and implementation. Each of these three ...

Abstract In this paper, we describe a CMOS DC-DC converter with a variable output voltage (8-12V @100mA) for a portable battery-operated system applications. The proposed DC-DC converter is used along with a Pulse-Frequency Modulation (PFM) method and consists of a reference circuit, a feedback resistor, a controller, and an internal oscillator. The integrated DC-DC converter with two external ...

In recent times, the way people access information from the web has undergone a transformation. The demand for information to be accessible from anywhere, anytime, has resulted in the introduction of Personal Digital Assistants (PDAs) and cellular phones that are able to browse the web and can be used to find information using wireless connections. However, the small display form factor of thes...

The effectiveness of interaction with mobile devices can be impacted by handedness; however, support for handedness in the interface is rarely provided. The goal of this article is to demonstrate that handedness is a significant interface consideration that should not be overlooked. Four studies were conducted to explore left-handed user interaction with rightor left-aligned scrollbars on perso...
