OFDM (Orthogonal Frequency Division Multiplexing) system is the high bandwidth efficient technique mainly used for high data transmission over the multipath fading environment. The major challenges faced by OFDM/OFDMA systems are sensitivity to frequency selective fading and ICI due to Doppler shift and CFO when subcarrier spacing becomes smaller. So we implement the zero padded conjugate techn...

Due to highly underdetermined nature of Single Image Super-Resolution (SISR) problem, deep learning neural networks are required be more deeper solve the problem effectively. One successful in (SR) is ResNet which can render capability with help skip connections. However, zero padding (ZP) scheme network restricts benefits connections SRResNet and its performance as ratio number pure input data...

Fugue is a cryptographic hash function designed by Halevi, Hall and Jutla and was one of the fourteen hash algorithms of the second round of NIST’s SHA3 hash competition. We consider Fugue-256, the 256-bit instance of Fugue. Fugue-256 updates a state of 960 bits with a round transformation R parametrized by a 32-bit message word. Twice in every state update, this transform invokes an AES like r...

in spite of the fact that cementitious and concrete materials are mainly used on a large scale and inhuge quantities for roads, dams, bridges and building constructions, the mechanical behavior of thesematerials depends to a great extend on structural elements and phenomena which are effective on amicro and nanoscale. although this is well known by researchers, material producers and engineersf...

BACKGROUND High plantar pressures are associated with the development of foot ulcers in people with diabetic neuropathy. The effect of terrain on plantar pressures during walking has not been fully explored. METHODS Twenty 23- to 40-year-old subjects with no known musculoskeletal pathology walked across three terrains: padded carpet (R), grass (G), and concrete (C) while wearing Novel Pedar (...

A 15-year-old Selle Francais gelding was presented to the equine referral hospital for treatment of a left guttural pouch mycosis previously diagnosed. After induction, the horse was shortly hoisted by all four feet, moved on a padded surgical table, and positioned in right lateral recumbency. In order to reduce the risk of bleeding during surgical manipulation of the carotid and maxillary arte...

a three-month-old male native puppy with lameness, metaphyseal swelling, pain, depression,inappetence and variable pyrexia was diagnosed as having hypertrophic osteodystrophy (hod) based onradiologic examination. the hemogram and biochemical profiles were within normal limits. radiologicexamination revealed a radiolucent zone in the metaphyses and a radiopaque band near the physes of theappendi...

This is a collection of classical results about resultants and discriminants for polynomials, compiled mainly for my own use. All results are well-known 19th century mathematics, but I have not investigated the history, and no references are given. 1. Resultant Definition 1.1. Let f(x) = anx n + · · ·+ a0 and g(x) = bmx + · · ·+ b0 be two polynomials of degrees (at most) n and m, respectively, ...

In this note, we present a collision attack on AURORA-512, which is one of the candidates for SHA-3. The attack complexity is approximately 2 AURORA-512 operations, which is less than the birthday bound of AURORA-512, namely, 2. Our attack exploits some weakness in the mode of operation. keywords: AURORA, DMMD, collision, multi-collision 1 Description of AURORA-512 We briefly describe the speci...

background and objective: mediastinal masses in children are a heterogenous group of asymptomatic potentially life-threatening congenital, infectious, or neoplastic lesions that present complex diagnostic and therapeutic dilemmas. materials and methods: the clinical and laboratory features of 65 patients who had open biopsies in ali-asghar hospital over 11 years were reviewed. results: seventy-...
