    通过试验和计算得到了RDX基复合炸药爆压、爆速、爆热和爆容等爆轰参数,分析了Al/AP摩尔比对复合炸药爆轰性能及爆轰能量释放的影响规律,得到了相应的经验计算公式.结果表明:随着Al/AP摩尔比的增大,复合炸药的爆热、做功能力示性数减小,而爆压、爆速及爆轰能量转化率增大.%The detonation parameters of RDX-based composite explosive, such as the detonation pressure, detonation velocity, detonation heat and detonation volume, were obtained by experiment and experimental calculation method. The influence rules of Al/AP mole scale on the detonation performances of composite explosive and detonation energy release were analyzed, and the correlative experimental calculation formula was deduced. The results showed the detonation beat and work capability factor decreased, while the detonation pressure, detonation velocity and detonation energy transformation efficiency increased with the Al/AP mole scale increasing.

    Objective. Sensorimotor rhythms (SMRs) are 8-30 Hz oscillations in the electroencephalogram (EEG) recorded from the scalp over sensorimotor cortex that change with movement and/or movement imagery. Many brain-computer interface (BCI) studies have shown that people can learn to control SMR amplitudes and can use that control to move cursors and other objects in one, two or three dimensions. At the same time, if SMR-based BCIs are to be useful for people with neuromuscular disabilities, their accuracy and reliability must be improved substantially. These BCIs often use spatial filtering methods such as common average reference (CAR), Laplacian (LAP) filter or common spatial pattern (CSP) filter to enhance the signal-to-noise ratio of EEG. Here, we test the hypothesis that a new filter design, called an ‘adaptive Laplacian (ALAP) filter’, can provide better performance for SMR-based BCIs. Approach. An ALAP filter employs a Gaussian kernel to construct a smooth spatial gradient of channel weights and then simultaneously seeks the optimal kernel radius of this spatial filter and the regularization parameter of linear ridge regression. This optimization is based on minimizing the leave-one-out cross-validation error through a gradient descent method and is computationally feasible. Main results. Using a variety of kinds of BCI data from a total of 22 individuals, we compare the performances of ALAP filter to CAR, small LAP, large LAP and CSP filters. With a large number of channels and limited data, ALAP performs significantly better than CSP, CAR, small LAP and large LAP both in classification accuracy and in mean-squared error. Using fewer channels restricted to motor areas, ALAP is still superior to CAR, small LAP and large LAP, but equally matched to CSP. Significance. Thus, ALAP may help to improve the accuracy and robustness of SMR-based BCIs.

    Full Text Available Desde hace un año, cuando comenzó a trabajar como portero del edificio dondevive el escritor Arturo Alape, en el barrio La Soledad, Luis se ha leído más de diezlibros bajo la orientación del maestro Alape, quien se siente muy orgulloso delúnico alumno de este taller de lectura casero. Luis, que cursó hasta segundo debachillerato en un pueblo de la Costa Caribe, no había hecho más que las lecturasobligadas del colegio hasta que tuvo contacto con la biblioteca del escritor. Bajosu guía, empezó por las novelas policíacas de George Simenon; siguió con GarcíaMárquez, Vargas Llosa, Jack London, Tolstoi, y hasta le hincó el diente alBogotazo de Alape. De Laura Restrepo se leyó la novela Leopardo al sol y escribióun ensayo animado por su mentor. Ahora está ávido de leer reseñas literariassobre esas novelas, para seguir su autoaprendizaje. Con tanta lectura, Luis diceque le cambió la vida y que ahora es uno de los pocos costeños que lee.

    Full Text Available Uma simulação de desmatamento e emissões de gases de efeito estufa no período 2007-2050 foi executada para a Área sob Limitação Administrativa Provisória (ALAP ao longo da rota da Rodovia BR-319 (Manaus-Porto Velho; uma área de 153.995 km² que representa aproximadamente 10% do estado do Amazonas. O governo federal, por meio do Ministério dos Transportes, anunciou a sua intenção de reconstruir e pavimentar a Rodovia BR-319, que está abandonada desde 1988. A Secretaria de Estado do Meio Ambiente e Desenvolvimento Sustentável (SDS, do Governo do Estado do Amazonas, e o Ministério do Meio Ambiente (MMA têm planos para criar uma série de áreas protegidas dentro da ALAP. Nossa simulação compara cenários com e sem as reservas de proteção propostas. A reconstrução e a pavimentação da rodovia são presumidas a serem finalizadas em 2011, com a abertura de estradas laterais associadas em datas especificadas ao longo do período 2014-2024. A simulação de desmatamento acopla os programas computacionais DINAMICA e Vensim, e incorpora uma série de inovações para permitir que o total de desmatamento responda à melhoria do acesso por estradas, baseado em uma parametrização da relação entre desmatamento e expansão viária observada em imagens de satélite de uma área no noroeste de Rondônia, adjacente à ALAP. A expansão modelada de estradas endógenas não está limitada por uma presunção de um processo de desmatamento puramente "dirigido pela demanda". Esta suposição impediu que outros modelos de desmatamento na Amazônia, representassem o efeito sobre o desmatamento total causado por decisões relativas às reservas (visto que o desmatamento total especificado externamente, baseado na demanda, implica em um "vazamento" de 100% de qualquer benefício de criação de reservas. A mesma limitação se aplica ao efeito de estradas em modelos dirigidos por demanda. Os resultados obtidos pelo nosso modelo foram validados

    Full Text Available Dynamic development of scheduling systems allows significantly improving currently realized tasks. Critical Chain Project Management (CCPM is one of the methods of project management basing on network planning. In this method is utilized the concept of a critical chain derived from the Theory of Constraints. This method allows avoiding losses considered project time and resources. It results in quicker project implementation (20-30%, and in reducing the risk level considered with tasks realization. The projects are cheaper, and the risk of cost overruns is significantly reduced. Factors that distinguish CCPM method from traditional network planning methods are: the balance of resources and the introduction of buffers. Moreover in the CCPM method key elements are: times of tasks that are reduced from traditional estimates to realistic ones. Activities associated with the task start as late as possible in accordance with the ALAP principle (As Late As Possible. This work presents the process of managing the assembly of a shearer machine taking into account the process of safety buffers utilization and the whole project optimization. It is presented the estimation of buffers capacity to obtain the improvement of project realization task.

    Juvenile blunt snout bream Megalobrama amblycephala with initial body weight of (0. 80±0. 02) g were randomly allotted into 36 tanks at a rate of 20 fish per tank and fed nine purified diets containing three linoleic acid (LA) levels (0. 5%, 1. 0% and 1. 5%) and three α-linolenic acid(ALA) levels (0. 5%, 0. 9% and 1. 3%) with tetraplication at water temperature of (27±3)℃ for 8 weeks. Weight gain, specific growth rate and protein ef-ficiency ratio were shown to be increased first and then decreased significantly with increase in dietary LA and ALA levels(P0 . 05 ) . The fish fed the diet containing 1. 3% ALA had significantly higher condition factor ( CF) than the other fish fed the diets containing ALA(P0.05); LA为1.0%组的鱼体肥满度显著高于其他两个LA组(P0.05); LA为0.5%组的肠道脂肪酶和蛋白酶活性显著低于其他两个LA组(P0.05)。研究表明,团头鲂幼鱼对 LA、 ALA 的需要量分别为1.0%~1.5%和0.5%~0.9%,当饲料中添加1.09%的LA和0.84%的ALA时,团头鲂幼鱼生长较好,各项生理机能指标正常。

    选取颗粒轨道模型,对Al/AP粉末颗粒在粉末火箭发动机内流动和燃烧进行三维数值模拟,为以Al粉末燃料和AP粉末氧化剂作为推进剂的新型燃烧室的设计以及实验研究提供参考。文中提出了一种粉末火箭发动机构型,通过对发动机燃烧室进行冷态和热态数值模拟,研究了氧燃比、Al粉末颗粒大小、燃烧室体积等因素对粉末火箭发动机燃烧室燃烧性能的影响。结果表明,一定范围内氧燃比较高时,燃烧室温度反而较低;较小粉末颗粒在燃烧室内更易离散;Al颗粒粒径越小越易燃烧,Al燃烧率也越高;验证了在Al/AP粉末火箭发动机的设计中引入特征长度来匹配Al粉粒径与燃烧室体积的合理性。%3D flow and combustion in the chamber of Al/AP powder rocket was numerically simulated by the particle trajectory model so as to provide reference for the design of the thrust chamber and the experimental investigation.The effects of oxidizer/fuel radio,particle diameter of Al and the volume of the combustion chamber were analyzed by a new engine configuration. The results show that the temperature of the chamber is lower when the oxidant/fuel ratio is higher in certain range,the combustion is easier when the particle of Al is smaller and the combustion efficiency of Al is higher. It is reasonable to choose an appropriate chamber characteristic length to adapt to the particle diameter of Al.

    Bevezetés: A gyermekek alvásideje az utóbbi száz évben csökkenést mutat. A csökkent alvásidő egészségre gyakorolt káros hatásai ismertek, magyarországi és romániai adatokkal azonban nem rendelkezünk a gyermekek alvásidejéről. Célkitűzés: A szerzők célul tűzték ki az alvással töltött idő felmérését Magyarországon és Romániában élő iskoláskorú gyermekek körében. Módszer: Saját szerkesztésű kérdőívvel 2446 gyermeket mértek fel. A kérdőívet Magyarországon egy nagyváros alap- és középfokú oktatási intézményeiben, Romániában egy általános és középiskolát magába foglaló intézményben osztották ki. Eredmények: Az átlagos alvásidő hétköznap 8,3±1,2 óra volt, amely a két országban szignifikáns különbséget mutatott (Magyarország vs. Románia, 8,5±1,2 óra vs. 7,8±0,9 óra, p = 0,001). A hétköznapokon mért alvásidő az életkorral negatív korrelációt mutatott (r = –0,605, p = 0,001), a hétvégi alvásidő esetében ez az összefüggés nem állt fenn. Következtetések: A vizsgálat az első, iskoláskorú gyermekek alvásidejét felmérő vizsgálat Magyarországon és Romániában. A két ország között talált különbségek hátterében életkori különbség állhat, de szerepe lehet a kulturális és életmódbeli különbségeknek, földrajzi fekvésnek is. Orv. Hetil., 2013, 154, 1592–1596.
