“…It is important to say that the application and manager were running on the same machine. More sophisticated approach in application development is shown in [21] Our configuration consisted of 3 dedicated executors and one manager. Manager was listening on a TCP/IP port 9000, which is the default.…”

Computational grids are useful tools for bringing supercomputing power to users by using idle resources in the network. In the following paper we give a short overview of architecture of the Alchemi grid developed on .Net platform. We created a grid application, which utilizes Rabin-Karp string searching algorithm to test Alchemi grid performances in situation when requests put diverse demands for computing resources to the different grid nodes. Scheduling and dispatching jobs to the computing resources is a critical activity of the grid software. We present a scheduling algorithm which showed performance improvements to the original algorithm shipped with Alchemi grid software.

Moving object detection, classification and tracking are more crucial and challenging task in most of the computer vision and machine vision applications such as robot navigation, human behavior analysis, traffic flow analysis and etc. However, most of object detection and tracking algorithms are not suitable for real time processing and causes slower processing speed due to the processing and analyzing of high resolution video from high-end multiple cameras. It requires more computation and storage. To address the aforementioned problem, this paper proposes a way of parallel processing of temporal frame differencing algorithm for object detection and contour tracking using the mixture of functional and domain decomposition parallel processing techniques. It has two main contributions. First, steps of frame differencing are parallelized using functional decomposition technique. Second, the processing of frames in each steps of frame differencing is again parallelized using domain decomposition technique. Finally, the performance is evaluated in Aneka Private Cloud platform and which yields to detect and track the object very swiftly and accurately.

As part of a comprehensive analysis, this case report presents a possible case of child maltreatment that can serve as a basis for forensic and medical examiner investigations. This case concerns the death of an infant who was approximately two months old. During a routine examination by the pediatrician at the end of May 2021, the child was found to have a normal head circumference of 31 cm. No other abnormalities were noted. On June 19, 2021, the child died, and an autopsy revealed a head circumference of 44 cm and a subdural hematoma as the cause of death. Questions arose as to who might have abused the child and when. The only evidence was a low-quality cell phone video taken by the child’s parents on June 13, 2021, six days before the child’s death, in which the child could be seen lying on a pillow. It was necessary to determine whether the child in this video already had an unnatural head circumference. This study presents a novel workflow that demonstrates how to analyze and deal with low quality video to answer questions like the above. The workflow demonstrates the creation of 3D scenes from digital image and video material. These 3D scenes can be used for object measurement and to support forensic and medical investigations. In the present case, where only low quality smartphone images were available, the presented workflow was used to create a 3D scene of the child lying on the pillow. In this 3D scene, it was possible to determine the child’s head circumference. These measurements support the findings of the medical examiner (dated June 24, 2021) and confirm the suspicion that possible child abuse had already taken place on June 13, 2021. The innovative approach makes it possible to identify evidence of possible abuse based on a specific point in time, in this case the child’s private footage. It also demonstrates the potential of 3D scene reconstruction in complex forensic and medical scenarios.
