The art of performance tuning is, alas, still an art; there are few tools to help predict the effects of changes that are motivated by performance needs. In this work, we present dynamic dependency modeling techniques for predicting the effects of configuration changes. These techniques utilize a simple, exterior model of the system under test, and only require codifying the nature of dependenc...

Checkpointing is a mostly used mechanism for supporting fault tolerance of high performance computing (HPC), but notorious in its expensive disk access. Parallel file systems such as Lustre, GPFS, PVFS are widely deployed on super computers to provide fast I/O bandwidth for general data-intensive applications. However, the unique feature of checkpointing makes it impossible to benefit from the ...

The security of any cryptography algorithm depends upon its key length and block size, by increasing the key length we actually enhance the security of the data being encrypted by a particular algorithm. Depending upon the requirements and confidentiality of the data we use the various cryptography algorithms available till now that may include DES .AES which is a successor of DES having 128-bi...

This paper examines the application of some techniques in Bluetooth communications expected to improve system’s performance under certain environmental conditions. The transmitter diversity Alamouti scheme [1] and receiver diversity have been evaluated and compared to the standard single antenna transmitter and receiver system by means of the achievable BER. Some analytical considerations about...

In this paper authors have presented a new approach to improve the performance of the glitch free cascadable adiabatic logic (GFCAL) circuit by replacing the triangular power supply with sinusoidal and trapezoidal power supplies (that control the charging and discharging of the capacitive load) and by sizing of transistors. A simulative investigation and performance analysis of proposed approac...

Results of survey of stakeholders regarding knowledge of and attitudes towards feed intake, efficiency and genetic improvement concepts" (2016).

to survive in today’s competitive environment, companies need continues improvement to achieve goals such as increasing the accuracy of targeting, improving product or service. however, there is no improvement guaranty without performance evaluation. an organization must assess current performance before embarking on any improvement. if it does not, it will have no baseline from which to determ...

Point-of-care testing is a rapidly evolving yet complex field. As your POCT program grows, take the time to understand the regulations, as they are important to ensuring patient safety. The regualtions established CLIA are designed to ensure consistent and reliable laboratory results that can accurately impact patient care. When beginning your look into POCY, first identify what labs can direct...

Companies today face the challenge of adopting proper supply chain sustainability (SCS) strategies and practices to respond effectively to emerging global sustainability initiatives. Business sustainability has become a strategic imperative, with a focus on both financial and non-financial sustainability performance, which creates shared value for all stakeholders. This paper examines the integ...
