Modern smartphones feature multiple applications which access shared data on the solid state storage within the device. As applications become more complex, contention over this memory resource is becoming an issue. This leads to increased battery drain as the applications are forced to touch the solid state device repeatedly after failing to retrieve or store data due to contention from other ...

In this position paper we describe an interface to incorporate application-specific knowledge for conflict resolution in an optimistically replicated file system. Conflicts arise in such systems because replicas of an object can be modified simultaneously in different network partitions. Application-specific knowledge is made available by the application writer in specialized tools called Appli...

given the scarcity of water resources using modern methods of irrigation in agriculture will be inevitable. today, process improvement, development and use of drip irrigation practices as one of the most advanced methods of irrigation in agriculture is increasing. so this study was conducted to determine the impacts of irrigation interval and drip irrigation method and their interactions on yie...

Data Envelopment Analysis (DEA) is a mathematical programming-based approach for evaluates the relative efficiency of a set of DMUs (Decision Making Units). The relative efficiency of a DMU is the result of comparing the inputs and outputs of the DMU and those of other DMUs in the PPS (Production Possibility Set). Also, in Data Envelopment Analysis various models have been developed in order to...

Optimism is a well-known technique to enhance the performance of distributed protocols. Optimistic approaches exploit properties exhibited by the system with certain likelihood, (i.e., that certain kinds of scenarios will prevail over others) to outperform the corresponding conservative protocol. These properties are usually referred as optimistic assumptions (e.g., an optimistic assumption is ...

Bootstrap confidence intervals on fixed-effects efficiency estimates from finite-sample panel data models exhibit low coverage probabilities, because the traditional estimate involves a "max" operator that induces a finite sample bias. Attempts to bootstrap confidence intervals for the traditional estimate have focused on correcting bias. Rather than addressing this bias at the bootstrap stage,...

In this paper Malmquist productivity index(MPI) for decision making unit(DMU) with interval data has been evaluated.A method for assessing Malmquist productivity index using cost efficiency also has been developed.The applicability of the methods developed is illustrated in the context of the analysis of groups of teaching of university performance.

In this paper, we suggest interval diagram techniques for formal verification of real-time systems modeled by means of timed automata. Interval diagram techniques are based on interval decision diagrams (IDDs)—representing sets of system configurations of, e.g., timed automata—and interval mapping diagrams (IMDs)— modeling their transition behavior. IDDs are canonical representations of Boolean...

In this paper, we study games with externalities. In the presence of externalities, the worth of a coalition depends on the coalition itself and a partition of the player set. In the presence of externalities, superadditivity is no longer sufficient for the efficiency of the grand coalition: some partitions may yield more surplus than the grand coalition. This result was indicated by Hafalir (G...
