Dynamic memory management is important and essential to the operation of a computer system. Efficient memory allocation, garbage collection and compaction are becoming increasingly critical in parallel, distributed and real-time applications using object-oriented languages like C++ and Java. In addition to achieving fast allocation/deallocation of memory objects, memory management techniques sh...

In today’s multicomputers, software overhead dominates the message-passing latency cost. We designed two multicomputer network interfaces that signif~cantiy reduce this overhead. Both support vMual-memory-mapped communication, allowing user processes to communicate without expensive buffer management and without making system calls across the protection boundary separating user processes from t...

The post-mortem state of a compromised system may not contain enough evidence regarding what transpired during an attack to explain the attacker’s modus operandi. Current systems that reconstruct sequences of events gather potential evidence at runtime by monitoring events and objects at the system call level. The reconstruction process starts with a detection point, such as a file with suspici...

Computational methods in memory array are being researched many emerging technologies to conquer the ‘von Neumann bottleneck’. Resistive RAM (ReRAM) is a non-volatile memory, which supports Boolean logic operation, and adders can be implemented as sequence of operations memory. While in-memory have recently been proposed, their latency exorbitant for increasing bit-width (O(n)). Decades researc...

Identity and collective memory is one of the fascinating subjects in modern sociology. In Iran, it arose again as modern and government-nation discourse emerged, and has been endlessly discussed since then. Such subjects have assumed an increasing importance due to the multi-cultural and multi-ethical existence of Iranian society and recent global developments. Accordingly, the present study ha...

This paper presents a textline detection method for degraded historical documents. Our method follows a conventional two-step procedure that the binarization is first performed and then the textlines are extracted from the binary image. In order to address the challenges in historical documents such as document degradation, structure noise, and skews, we develop new methods for the binarization...

In this paper, we describe an input sensitive thresholding algorithm for ancient Hebrew calligraphy documents. Usually, historical document images are of poor quality since the documents have degraded over time due to storage conditions. However, the distribution of noise in one document is not uniform and the characters quality may vary. We develop tools to identify noisy characters and apply ...

In this chapter, a binarization technique specifically designed for historical document images is presented. Existing binarization techniques focus either on finding an appropriate global threshold or adapting a local threshold for each area in order to remove smear, strains, uneven illumination etc. Here, a hybrid approach is presented that first applies a global thresholding technique and, th...
