Machines are a key element in the production system and their failure causes irreparable effects in terms of cost and time. In this paper, a new multi-objective mathematical model for dynamic cellular manufacturing system (DCMS) is provided with consideration of machine reliability and alternative process routes. In this dynamic model, we attempt to resolve the problem of integrated family (par...

How did we arrive at our current state of tHe art? Pre-Cellular Mobile Telephony In order to understand where we're going, we need to understand how we arrived at today's state of the art. The notion of reliable mobile telephone service was first introduced in the 1950's. The first widely deployed system was developed by AT&T Bell Laboratories in the United States and referred to as Mobile Tele...

Based on cellular automata (CA), the diffusion of communication products, namely the mobile phone (MP) and the landline telephone (LT), were modeled and simulated. The ordinary least squares (OLS) procedure and nonlinear regression method were carried out to estimate the diffusion parameters. The predicted results were compared with the actual data. It is found that: (1) the diffusion processes...

for planting fine seeds in cellular trays, an automatic pneumatic seeder was designed, constructed and evaluated. catia software was used to design and analysis the system parts of the seeder. different parts of the seeder, including vibrating seed hopper, vacuum boom, seed picking nozzles, seed tube, pneumatic system and electronic control unit for automation of the seeder, were designed and c...

Fast development in Information Communication Technology (ICT) and cellular telephone innovations empower users to perform online transactions from cell telephones/machines from anyplace, at whenever. Thus users need to oversee various online records. Thusly users key-in numerous login data to verify/access them. Consequently it is troublesome for users to oversee various online record accredit...

PhoneStation is a system that provides a Sun Microsystems SPARCstation† with complete control over an ordinary telephone line. It consists of a telephone line interface unit with loop control and touch tone detection, a suite of supporting software libraries that include digital signal processing for call progress monitoring, text-to-speech conversion, telephone line control, 2. PhoneStation Sy...

Automatic transcription of telephone speech involves additional challenges compared to wideband data processing, mainly due to channel limitations and to particular characteristics of conversational telephone speech. While in TV speech recognition applications, such as automatic transcription of broadcast news, the presence of telephone data is nearly insignificant (less than 1 %), in most radi...
