摘要:
一台ENERGY POWER12 SUB低音炮,声音断断续续。上电试机,测量+30V电压波动明显,怀疑功放芯片TDA7294过热损坏,但断电测量其引脚对地阻值均正常。断开功放芯片的±30V供电线后上电,发现±30V电压波动幅度较小,但±30V电压有10V的波动幅度。

摘要:
成立仅二十几年的美国狄芬尼提品牌作为音箱界的新贵,有音箱界的特斯拉之美誉,其音箱在欧美中高端音响市场占有较大份额。PROSUB 60有源低音炮采用8英寸扬声器,箱体体积小巧,但其功率强劲,低音深潜,笔者实绘其电路(元件号为笔者自编,元件值为实测值),分析其工作原理,供同行参考。

摘要:
一台JBLSUB140有源音响(低音炮),开机后指示灯亮,约2s后有继电器吸合声,但无声。本机功放部分采用分立元件组成OCL输出电路(输出端没有隔直流电解电容),其特点是在信号传输通道中没有耦合电容,低频效果较好,特别适合低音炮功放,但供电须采用正负供电。

摘要:
笔者开始接触家庭影院器材的时候,曾有朋友向我咨询中等面积的听音环境,但是家居杂物较多,不想用太多地方放置器材,想要一款既小型,低频又不错的超低音。这可难倒了我,毕竟大尺寸单元更容易做到优质的低频,我当时认识的器材并不多,一时想不到有什么品牌的小型又强力的超低音。最后朋友还是妥协选择了常规尺寸的大方块型超低音,但我也从此对小体积的影院产品特别留意。S0NANCE的S10SUB-1吸引了我的注意力:它会不会就是我所期待的超低音呢?

摘要:
In this paper, we utilized the Jaulent-Miodek equation which is one of important models in particle physics and engineering. The exact traveling wave solutions for this equation “involving parameters” according to two different techniques are constructed. When these parameters are taken as special values, the solitary wave solutions are derived from it. A comparison between the obtained results using these two different methods with that obtained by previous authors is demonstrated.

摘要:
For decades, Taenia solium cysticercosis (TSC) has remained an important constraint for public health and economic well being of the predisposed communities. Despite the fact that the disease is easily preventable, humans remain foci for transmission. They harbour the mature form of the parasite (Taenia solium) which may be curable at this stage and also easily prevented from contaminating pig feeds and environment with eggs of the parasite to break the cycle. Researchers, knowledgeable communities and international organisations such as the World Health Organisation work hard to make the disease a history. Nevertheless, persistence of the disease in endemic regions such as sub Saharan Africa is kept on increasing. While TSC in human may serve as a silent killer as it can go unnoticed for years, the immanent social cultural settings and lifestyles of the communities in endemic areas form the main concern on the epidemiology of the disease. Unless lifestyles change in endemic regions, front line research might rarely find its way into applications in an area of huge societal and economic impact, the TSC epidemiology. Sincerely, transmission of TSC is favoured by poor sanitation and hygiene which is motivated by lifestyle and poverty. What is perhaps missing is the knowledge on “why is the communities involved ease indiscriminately while almost every member of the community in endemic areas knows that indiscriminate defecation may harm their health? What social drivers are behind this motive (bush defecation)? How best can the disease be controlled and monitored? This review recommends for developing and implementing an interdisciplinary OneHealth community-based control mechanism and monitoring (surveillance) programme as standpoints towards eliminating TSC in sub-Saharan Africa and the rest endemic regions.

摘要:
Pseudo-random sequences with long period, low correlation, high linear complexity, and uniform distribution of bit patterns are widely used in the field of information security and cryptography. This paper proposes an approach for generating a pseudo-random multi-value sequence (including a binary sequence) by utilizing a primitive polynomial, trace function, and k-th power residue symbol over the sub extension field. All our previous sequences are defined over the prime field, whereas, proposed sequence in this paper is defined over the sub extension field. Thus, it’s a new and innovative perception to consider the sub extension field during the sequence generation procedure. By considering the sub extension field, two notable outcomes are: proposed sequence holds higher linear complexity and more uniform distribution of bit patterns compared to our previous work which defined over the prime field. Additionally, other important properties of the proposed multi-value sequence such as period, autocorrelation, and cross-correlation are theoretically shown along with some experimental results.
