All-window data liveness

Pengcheng Li, Chen Ding
2013 Proceedings of the ACM SIGPLAN Workshop on Memory Systems Performance and Correctness - MSPC '13  
The paper gives a linear-time algorithm to compute the average liveness for all window lengths and discusses potential uses of the new metric.  ...  This paper proposes a new metric called all-window liveness, which is the average amount of live data in all time windows of a given length.  ...  The joint study of liveness and locality also helps to understand cache replacement algorithms. A related metric is the generalized working set (GWS) [2] . GWS is defined by the time-space product.  ...

Hybrid Symbolic Regression with the Bison Seeker Algorithm

Jan Merta
2019 MENDEL  
The results of the current study support the fact that the local algorithm accelerates evolution, even with a few iterations of a Bison Seeker Algorithm with small populations.  ...  Consequently, local learning is used to tune model parameters. Such tuning of parameters represents the lifetime adaptation of individuals.  ...  Acknowledgement: The work has been supported by the Funds of University of Pardubice (by project "SGS 2019" No: SGS_2019_021), Czech Republic.

Empirical study of the dynamic behavior of JavaScript objects

Shiyi Wei, Franceska Xhakaj, Barbara G. Ryder
2015 Software, Practice & Experience  
The dynamic characteristics of JavaScript pose software engineering challenges such as program understanding and security.  ...  Despite the popularity of JavaScript for client-side web applications, there is a lack of effective software tools supporting JavaScript development and testing.  ...  In our study, we analyzed a larger set of web applications and focused on the behavior of JavaScript objects, not functions.  ...

Safely Extending Procedure Types to Allow Nested Procedures as Values [chapter]

2003 Lecture Notes in Computer Science  
The concept of nested procedure values, i. e., the possibility of using nested procedures as values of procedure types, is a useful and powerful concept.  ...  the benefits of the concept, alternative language rules as well as a small language extension for Oberon-2 are suggested, which allown ested procedures to be safely used as values of procedure types and  ...  But since pure functional languages lack the notion of variables to which closures might be assigned, the problem of dangling closures can only appear when a function returns a locally defined function  ...

Optimum routing and scheduling for estimation in wireless sensor networks

Amir Hossein Mohajerzadeh, Vahid Fakoor, Mohammad Hossein Yaghmaee, Elham Mirfarah
2012 2012 2nd International eConference on Computer and Knowledge Engineering (ICCKE)  
The main goal is to maximize network lifetime where it consists of a fusion center and a set of sensor nodes.  ...  In order to prolong network lifetime, we determine the optimal number of active sensor nodes and the number of samples provided by each of them using linear optimization problem.  ...  In WSN, sensor nodes collect real data, perform a local data compression and then send them to the FC. FC gathers data and produces a final estimation of the observed parameter.  ...

Gelenbe, who invited me to write this paper and then patiently pored through the lengthy draft.  ...  For two of the programs, a compiler and an assembler, the LRU lifetime dominated the WS lifetime near the LRU primary knee. These two programs had strong cycles of use of their locality sets.  ...  Inasmuch as optimal operation seems to be correlated with operating a program at the primary knee of the lifetime function [74] , and inasmuch as neither ofthese lifetime models accurately represents  ...
