background a large amount of money is allocated to hypertension in terms of remedial and care costs, but fighting against this disease begins with education. objectives this study has been conducted with the aim of comparing the effect of two methods: face-to-face education and distance education (via short message service [sms]) on amount of following remedial diet in patients suffering from h...

the present study has been conducted on shemiranat county landscape, using lattice hexagon approach, for the first time, in order to achieve homogeneous units in degradation model. to this aim, with respect to the extent of the studied area, a lattice hexagon composed of 36 units (cells) was created and each grid cell was considered as a sub landscape. next, ecological vulnerability, degradatio...

in the last few years, public awareness has been on the increase about short- and long-term effects of forest roads construction on the environment. therefore, forest road managers have to be concerned about the negative impacts and mitigate them as much as possible. this research conducted multi-criteria analysis techniques in a useful way to define the effective criteria and propose a model f...

Because fault core zones and damage overlap, when a tunnel crosses the intersecting faults groundwater flow characteristics of tunnel-surrounding rock will be different compared to that from single fault. By using theory “Three-district zoning faults”, an improved Darcy–Brinkman numerical model for crossing was established in this work. Based on relative vertical positions between axis intersec...

I revisit the fault-tolerance of cyclic redundancy checks (CRCs), expanding on the work of Driscoll et al [1]. I introduce the concepts of Schrödinger-Hamming weight and Schrödinger-Hamming distance, and I argue that under a fault model in which stuck-at-one-half or slightly-out-of-spec faults dominate, current methods for computing the fault detection of CRCs may be over-optimistic. Keywords-c...

This paper presents a new fast-acting backup protection strategy for future hybrid ac-dc distribution networks. By examining the impedance measured by distance relay measuring from “ac-side” of network, unique characteristic is established faults occurring on “dc-side” an embedded medium-voltage dc (MVDC) link, interconnecting two 33 kV network sections. Based identified characteristic, appropr...

structural evolution of alborz has already been mentioned by many researchers all over the world. central alborz is located in the bending of the eastern and the western alborz. damavand volcano is situated in the bending part along the great and active faults such as mosha, north of baijan, ask, nava and ira. the nava and ira faults are in the eastern side of damavand volcano with a trend of e...
