We present a 55-year old male patient who was subjected to whole body skeletal scintigraphy for metastatic work up of urinary bladder cancer. Whole body 99mTc-methylene diphosphonate (MDP) skeletal scintigraphy was performed. That revealed no skeletal metastasis in the entire body skeleton and normally visualized left kidney with empty right renal fossa. Additionally tracer activity ...

Network topology is one of the major factors in defining behavior a network. In present scenario, demand for network security has increased due to an increase possibility attacks by malicious users. this paper, blockchain-based system suggested securely discovering and storing networks. Techniques such as cloud-based storage systems are not efficient lacking trust, privacy, security, data contr...

in this paper we study necessary and sufficient conditions for some types of linear combinations of wave packet frames to be a frame for l^2(r^d). further, we illustrate our results with some examples and applications.

Smart cities are expected to significantly improve people's quality of life, promote sustainable development, and enhance the efficiency operations. With implementation many smart devices, c problems have become a serious challenge that needs strong treatments, especially cyber-attack, which most countries suffer from it. My study focuses on security city systems, include equipment like air con...

ABSTRACT We present a method for applying spatially resolved adiabatic and radiative loss processes to synthetic radio emission from hydrodynamic simulations of sources active galactic nuclei (AGNs). Lagrangian tracer particles, each representing an ensemble electrons, are injected into the position, grid pressure, time since last strong shock recorded. These quantities used track losses electr...

In network steganography methods based on packet length, the length of the packets is used as a carrier for exchanging secret messages. Existing methods in this area are vulnerable against detections due to abnormal network traffic behaviors. The main goal of this paper is to propose a method which has great resistance to network traffic detections. In the first proposed method, the sender embe...

usually in the form of parallel processing with parallel multi-processor systems are designed .for this reason irregular flow may occur with packages. when you're tired and it all comes out in his np (network processors)  system, reset depending on network performance is negatively affected and we delayed to do this, the design of processors working in parallel packet transmission by avoid...

Packet Tracer (PT) is an official Cisco software simulator for exercising Cisco network equipment. Graphical Network Simulator (GNS3) is a free emulator software which allows running actual networking software images on a computer. Both provide good Graphic User Interface (GUI) design and have been intensively used for learners to build, configure, and troubleshoot networks in a virtualized net...

This study aims to model the network for archipelago and tourism on Gili Ketapang. The implemented is a wireless WAN infrastructure meet needs of reliable tourist area. implements DHCP OSPF as routing protocol. methodology used perform simulations using packet tracer in designing through several scenarios with parameters assessing delay loss. At time implementation, it began cluster area number...
