a secular milestone is approached by the world in line of reaching millennium development goals (mdgs). after december 2015, a new of flexible and global sustainable development goals (sdgs) were set, replace mdgs by sdgs. infant mortality rate (imr) is a pivotal indicator of development in a given country that embedded in millennium development goal (mdg).  after that in manner of strong clini...

this study considers scheduling in hybrid flow shop environment with unrelated parallel machines for minimizing mean of job's tardiness and mean of job's completion times. this problem does not study in the literature, so far. flexible flow shop environment is applicable in various industries such as wire and spring manufacturing, electronic industries and production lines. after mode...

Prompted by the increasing requirement for the fast but precise and detailed digital documentation of archaeological excavations and heritage artifacts, in this article we report our latest experience in capturing detailed 3D geometric information of two sites in Tuscany, Italy, using the image-based approach. We present a 3D recording flow-line, based on multi-image matching, capable of retrie...

The paper describes the implementation of a systolic array for a multilayer perceptron on different FPGA architectures with a hardware-friendly learning algorithm: Pipelined On-line Backpropagation. By exploiting the embedded memories of certain families alongside the projection used in the systolic architecture, we can implement a very large interconnection layers. These physics and architectu...

Introduction: Horizontal root fracture (HRF) generally has a good prognosis of healing at fracture line after repositioning and flexible splinting. However, various factors such as delayed referral may unfavorably influence close reduction of firmly displaced coronal fragments and the long-term prognosis of healing at fracture line. Case 1: A 25-year-old woman with HRF in her maxillary central ...

Nowadays, flexible manufacturing system (FMS) is introduced as a response to the competitive environment. Scheduling of FMS is more complex and more difficult than the other scheduling production systems. One of the main factors in scheduling of FMS is variable time of taking orders from customers, which leads to a sudden change in the manufacturing process. Also, some problems are created in p...

This study considers outsourcing decisions in a flexible flow shop scheduling problem, in which each job can be processed by either an in-house production line or outsourced. The selected objective function aims to minimize the weighted sum of tardiness costs, in-house production costs, and outsourcing costs with respect to the jobs due date. The purpose of the problem is to select the jobs tha...

The complete 3D nonlinear dynamic problem of extensible, flexible risers conveying fluid is considered. For describing the dynamics of the system, the Newtonian derivation procedure is followed. The velocity field inside the pipe formulated using hydrostatic and Bernoulli equations. The hydrodynamic effects of external fluids are taken into consideration through the nonlinear drag forces in var...

This paper discusses the control of flexible microgrids, consisting of a Redox Flow Batteries (RFB) and a new power conditioning system (PCS) for the RFB. Considering the importance of energy storage, this study is essential in power systems that are developed cautiously. RFB is connected to power system by a DC/DC or DC/AC converter to produce a DC voltage. It is very important that this conve...

In this paper, an exact geometric algorithm is presented for solving two-job sequencing and scheduling problems in flexible flow shop and job shop environments while the resources are (un)available in some time periods and processors (un)availability is the same in all work centers. This study seems utterly new and it is applicable to any performance measure based on the completion time. The in...
