Simha, R. and A. Majumdar, On Lookahead in the List Update Problem. Information Processing Letters. We study a problem in the area of self-adjusting data structures: algorithms for the singly-linked list for the case in which a sequence of operations is to be performed on the list and the entire sequence is known beforehand. Whereas past approaches assume that the cost of lookahead is zero, we ...

â  ba ckground the only curative therapy for end-stage liver disease is transplantation but due to a shortage of available donor livers the waiting list mortality is high. this study aimed to evaluate the outcome and characteristics of patients on the waiting list for liver transplantation in shiraz, southern iran during the period from april 2004 to march 2007. methods medical records of all c...

The Arabic language is characterized by its rich and complex morphology based on root-pattern schemes. Root extraction is one of the most important topics in the context of natural language processing applications such as information retrieval, text processing, machine translation, speech tagging, etc. This paper presents a method to extract the trilateral roots of Arabic words, acting from the...

For a long time, optimal competitive factors of online algorithms used to be approximated by manually finding and improving upper and lower bounds. The concept of a competitive ratio approximation scheme (CRAS), introduced by Günther et al. in 2012 [13], defines a method of reducing this process to a task that can be executed automatically by a computer up to an arbitrarily good precision: A CR...

In the Information era, optimization of processes for Information Retrieval, Text Summarization, Text and Data Analytic systems becomes utmost important. Therefore in order to achieve accuracy, extraction of redundant words with low or no semantic meaning must be filtered out. Such words are known as stopwords. Stopwords list has been developed for languages like English, Chinese, Arabic, Hindi...

the effectiveness of any drug supply systems in providing a trustworthy supply of essential drugs is a critical issue. to evaluate this effectiveness, it is necessary to watch over the status of the essential medicines in any country impartially and continuously. some countries and also the world health organization (who) have codified a list of minimum medicines needed for a basic health care ...

Interdependence of tasks in a mission necessitates information flow among the organizational elements (agents) assigned to these tasks. This information flow introduces communication delays. An effective task schedule that minimizes the total execution time, including task processing and coordination delays, is an important issue in designing an organization and its task processing strategy. Th...

Are there fundamental differences in the way in which a list of pictures and a list of words are processed? We report three experiments that examine serial position effects for rapidly-presented naturalistic scenes. The experiments provide a basis for comparison with the U-shaped serial position curve and list-length effect which typically result from verbal learning experiments. In contrast to...
