VoIP, one of emerging technologies, offers high quality of real time voice services over IP-based broadband networks; however, the quality of voice would easily be degraded by IP network impairments such as delay, jitter and packet loss, hereon initiate the presence of new technologies to help solve out the problems. Among those, playout buffer at the receiving end can compensate for the jitter...

Congestion in router buffer increases the delay and packet loss. Active Queue Management (AQM) methods are able to detect congestion in early stage and control it by packet dropping. Effective Random Early Detection (ERED) method, among many other AQM methods, gives a good performance in detect and control congestion and preserve packet loss. However, the ERED neglect the delay factor, which is...

sensitivity of tomato fruits to chilling injury limits its storage and marketability. this study investigated the effect of hot water treatment (hwt) on reducing the consequences of chilling injury (ci) with respect to quality attributes of tomatoes during storage. tomatoes were harvested at three ripening stages: mature green, pink, and red; dipped in hot water at 45°c for 15 min; and stored a...

In today’s fast marketing over the Internet or online, many retailers want to trade at the same time and change their marketing strategy to attract more customers. Some of the customers may decide to cancel their orders partially with a retailer due to various reasons such as increase in customer’s waiting time, loss of customer’s goodwill on retailer’s business, attractive promotional schemes ...

A packet transmission delay is an important quality characteristic for various applications including real-time and data applications. In particular, it is necessary to investigate not only a whole distribution of the packet transmission delay, but also the tail part of the distribution, in order to detect the packet loss. In this paper, we analyze the characteristics of the tail part of packet...

In the field of management, the delay within projects is a prominent and contentious issue. Due to the fact that delay leads to cost and time over-runs, it is often the subject of litigation claims and creation of managerial tensions. In a bid to bring such delays under control and also to diminish managerial tensions, it is necessary to recognize and understand the following four concepts:"typ...

A novel algorithm for buffer management and rate allocation is presented for providing loss and delay differentiation for traffic classes at a network router. The algorithm, called JoBS, provides delay and loss differentiation independently at each node, without assuming admission control or policing. Contrary to most existing algorithms, scheduling and buffer management decisions are performed...
