In this paper we tackle the optimal control problem for piecewise linear and hybrid systems by using a computational approach based on performance-driven reachability analysis. The idea consists of coupling a reachset exploration algorithm, essentially based on repetitive use of linear programming, to a quadratic programming solver which selectively drives the exploration. In particular, an upp...

In this paper, we consider the Type-II Hybrid ARQ schemes with the LDPC codes having the rate of 0.5 through MIMO-OFDM Spatial Multiplexing (SM) schemes for high speed and high throughput transmission. MMSE nulling and MLD are used for the signal separation and detection method in SM. We also have used the channel estimation per subcarrier with MMSE criterion. The uncoded Hybrid ARQ schemes wit...

This paper presents a theoretical basis for global transaction scheduling to maintain global serializability in multidatabase systems. Three correctness criteria. are formulated to utilize the intrinsic characteristics of global transactions at the global level to determine the serialization order of global subtransa.ctions at each local site. In particular, two new types of serializability, ch...

Hybrid sorting immune simulated annealing technique (HSISAT), a Meta heuristic is proposed for solving the multi objective flexible job-shop scheduling problem (FJSP). The major objectives are distributing the time of machines among the set of operations and scheduling them to minimize the criterion (makespan, total workload and maximum workload). The processing time is sorted for isolating the...

The present study seeks to evaluate a hybrid model of identification that incorporates response-to-intervention (RTI) as a one of the key symptoms of reading disability. The one-year stability of alternative operational definitions of reading disability was examined in a large scale sample of students who were followed longitudinally from first to second grade. The results confirmed previous fi...

A hybrid error model with L1 and L2 norm minimization criteria is proposed in this paper for image/video super-resolution. A membership function is defined to adaptively control the tradeoff between the L1 and L2 norm terms. Therefore, the proposed hybrid model can have the advantages of both L1 norm minimization (i.e. edge preservation) and L2 norm minimization (i.e. smoothing noise). In addit...

This paper is concerned with a dynamic vehicle routing problem. The problem is dynamic in the sense that the time it will take to traverse each edge is uncertain. The problem is expressed as a bi-criterion optimisation with the mutually exclusive aims of minimising both the total mean transit time and the total variance in transit time. In this paper we introduce a hybrid dynamic programming an...

In this paper, we present a hybrid method combining Tabu Search (TS) optimization algorithm with the Very Fast Simulated Annealing (VFSA) procedure for the Job-shop Scheduling Problem (JSP). Tabu search algorithms are among the most effective approaches for solving the job shop scheduling problem which is one of the most difficult NP-complete problems. However, neighborhood structures and move ...

this paper aims to present a model for agile supply chain model in construction enterprises with performance evaluation of suppliers and contractors. management and selection of suppliers and contractors plays an important role in process of constructions, because contractors are as corner stones of construction projects. also, contractors are the main factor in converting resources to the fina...

The decision data of human judgments with preferences are often vague in many real life cases. Human judgments with preferences are often unclear and hard to estimate by exact numerical values. So that the traditional ways of using crisp values are inadequate. The relationship among criteria and choosing and rating alternatives based on criterion are often expressed in terms of linguistic terms...
