پژوهشگران اخیراً پنل‌های چندلایه‌ی متشکل از الوارهای متقاطع چوبی (C‌L‌T) را به عنوان یکی مناسب‌ترین ماده‌های ساختمانی دارای کمترین اثرات منفی زیست محیطی معرفی کرده‌اند. در طرح سازه‌ی ترکیبی فولادی ـ ارائه شده پژوهش حاضر، قاب ساختمان نوع بوده و برای کف‌ها دیوارهای برشی سازه افقی قائم C‌L‌T استفاده است. جهت بررسی عملکرد سیستم ای پیشنهادی، یک ۶ طبقه با دو باربر جانبی شامل: الف) خمشی متوسط دیافراگم ...

We present a T E X macro package for generating the arabic writing from a standardized ASCII input notation. It can handle partial or full vocalization, and generates automatically most of the common ligatures. There is limited support for Farsi, Urdu, and Pashto. ArabT E X is compatible with Plain T E X and also most L a T E X environments; arabic and other material can be mixed freely. For sp...

macroH2A is an H2A variant with a highly unusual structural organization. It has a C-terminal domain connected to the N-terminal histone domain by a linker. Crystallographic and biochemical studies show that changes in the L1 loop in the histone fold region of macroH2A impact the structure and potentially the function of nucleosomes. The 1.6-A X-ray structure of the nonhistone region reveals an...

The following propositions are true: (1) Let X be a set, p be a permutation of X, and x, y be elements of X. Then p +· (x, p(y)) +· (y, p(x)) is a permutation of X. (2) Let f be a function and x, y be sets. Suppose x ∈ dom f and y ∈ dom f. Then there exists a permutation p of dom f such that f +· (x, f(y)) +· (y, f(x)) = f · p. Let X be a finite non empty subset of R. The functor minX yielding ...

MzScheme’s continuation marks provide a flexible mechanism for implementing a number of useful language features and tools. We demonstrate the simplicity and utility of continuation marks by adapting them for JavaScript as frame-based stack marks using the Rhino implementation, showing a simple model of their behavior, and using them to build a toy debugger. Along the way, we discover a few int...

It is known that the essential ingredients of a Lisp-style unhygienic macro system can be expressed in terms of advanced hygienic macro systems. We show that the reverse is also true: We present a model of a core unhygienic macro system, on top of which a hygiene-compatible macro system can be built, without changing the internals of the core macro system and without using a code walker. To ach...

The paper presents an algorithm for multi-agent strategic modeling (MASM). The method applies domain knowledge and transforms sequences of basic multi-agent actions into a set of strategic action descriptions in the form of graph paths, agent actions, roles and corresponding rules. The rules, constructed by machine learning, enrich the graphical strategic patterns, which are presented in the fo...
