Preprocessing of character images is an important step in recognition. We describe a method of enhancing binary character images to assist the subsequent recognition process in both handwritten and machine-printed documents. The method performs selective and adaptive stroke "filling" with a neighborhood operator which emphasizes stroke connectivity. An improvement of 7% points was realized in r...

Multiple Input and Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) system have the potential to achieve very high capacity depending on the propagation environment. The objective of this paper resource allocation on LTE using is the adaptive resource allocation in MIMOOFDM system using the water filling algorithm. Water filling solution is implemented for allocating...

An opportunistic transmission scheduling scheme is proposed to make better use of the multiuser diversity gain in a MIMO system. The performance of a MIMO link is quantified by its information-theoretic capacity. Even though the base station has no knowledge of the transmission channel, the proposed algorithm generates a transmission randomizing matrix according to the distribution of the chann...

Vehicle (bike or car) sharing represents an emerging transportation scheme which may comprise an important link in the green mobility chain of smart city environments. This chapter offers a comprehensive review of algorithmic approaches for the design and management of vehicle sharing systems. Our focus is on one‐way vehicle sharing systems (wherein customers are allowed to pick‐up a vehicle at...

We characterize the rate coverage distribution for a spectrum-shared millimeter wave downlink cellular network. Each of multiple cellular operators owns separate mmWave bandwidth, but shares the spectrum amongst each other while using dynamic inter-operator base station (BS) coordination to suppress the resulting cross-operator interference. We model the BS locations of each operator as mutuall...

Runoff is one of the most important components hydrological cycle, and having complete series runoff data essential for any modelling process. This study aims to estimate at Al-Jawadiyah hydrometric station using artificial neural networks. used only in addition values measured Al-Amiri on Syrian-Lebanese border. Many experiments were conducted a very large number networks trained with changing...

Multiple operators commonly coexist in one-way carsharing systems. Therefore, the performance of system is worth exploring. We used systems with two as an example, assuming that one joins first and called leader, another named follower. A nonlinear mixed-integer bilevel programming model set to jointly optimize allocations (including number shared cars parking spaces) relocations. The users’ pr...

One of the main challenges of the arising wireless world is to support a wide set of QoS-demanding services. However, the solutions that will be considered should not only take into consideration the optimization of the network performance, but should also be energy efficient both for the operator and the end-user. This paper presents the concept of Opportunistic Networks (ONs) as an energy eff...
