In today's fiercely competitive products market, product warranty has started playing an important role. The warranty period offered by the manufacturer/dealer has been progressively increasing since the beginning of the 20th Century. Currently, a large number of products are being sold with long-term warranty policies in the form of extended warranty, warranty for used products, service contra...

From the observation that users reading news tend to not click outdated news, we propose notion of 'lifetime' with two hypotheses: (i) has a shorter lifetime, compared other types items such as movies or e-commerce products; (ii) only competes whose lifetimes have ended, and which an overlapping lifetime (i.e., limited competitions). By further developing characteristics then present novel appr...

The SPIN extension presented in this article is meant as a way to facilitate the modeling and verification of object-oriented programs. It provides means for the formal representation of some run-time mechanisms intensively used in OO software, such as dynamic object creation and deletion, virtual function calls, etc. This article presents a number of language extensions along with their implem...

Battery Management System (BMS) requires an indefinite accurate model. With an aging model, the lifetime of a battery can be precisely predicted. The mathematical model in terms of state variables is presented in this preliminary work involving smart BMS system. This work is crucial as the state space model is able to mimic the complex dynamic behavior of a battery system. A numerical case stud...

The ‘SemanticLIFE’ system is designed to store, manage and retrieve ones lifetime’s information entities. It enables the acquisition and storage of data while giving annotations to email messages, browsed web pages, phone calls, images, contacts, life events and other resources. ‘SemanticLIFE’ also provides intuitive and effective search mechanism based upon stored semantics. This paper present...

This paper presents a dynamic energy management policy for a wireless video streaming system, consisting of battery-powered client and server. The paper starts from the observation that the video quality in wireless streaming is a function of three factors: encoding aptitude of the server, decoding aptitude of the client, and the wireless channel. Based on this observation, the energy consumpti...

background: disease-modifying drugs (dmds) are a significant expenditure for treating multiple sclerosis (ms). however, there is limited report on assessment of the cost-utility of dmds compared with symptom management in the presence of long-term data. this study aimed to assess the lifetime cost-utility from the iranian healthcare perspectives of 4dmds relative to symptom management alone in ...

Object-oriented applications of database systems require database transformations involving non-standard functionalities such as set manipulation and object creation, i.e., the introduction of new domain elements. To deal with these functionalities, Abiteboul and Kanellakis introduced the \determinate" transformations as a generalization of the standard domain-preserving transformations. The ob...

Battery lifetime has become one of the top usability concerns of mobile systems. While many endeavors have been devoted to improving battery lifetime, they have fallen short in understanding how users interact with batteries. In response, we have conducted a systematic user study on battery use and recharge behavior, an important aspect of user-battery interaction, on both laptop computers and ...
