Brain Workshop - a Dual N-Back game Introduction    -    Download    -    Tutorial    -    Details & Options    -    Donate Brain Workshop is a free open-source version of the dual n-back brain training exercise. What if a simple mental exercise could improve your memory and intelligence? A 2008 study published in the PNAS scientific journal shows that a memory task called  dual n-back may improve working memory (short term memory) and fluid intelligence . These findings are important because fluid intelligence was previously thought to be unchangeable. Those findings have since been replicated twice with strongly positive results, and two more times in smaller studies with weaker, but still positive, results. Brain Workshop implements this dual n-back task , and allo...

Constitution and the Right of Self-Defense Since the end of World War II, Japan made a decision not to repeat the ravages of war and has worked hard, aiming to build a peace-loving nation. The Japanese people desire lasting peace, and the principle of paci sm is enshrined in the Constitution, of which Article 9 prescribes the renunciation of war, the possession of war potential, and the right of belligerency by the state. Of course, since Japan is an independent nation, these provisions do not deny Japan’s inherent right of self-defense as a sovereign state. Since the right of self-defense is not denied, the Japanese Government interprets this to mean that the Constitution allows Japan to possess the minimum level of armed force needed to exercise that right. Therefore, Japan, under the Constitution, maintains the Self-Defense Forces (SDF) as an armed organization, holding its exclusively national defense-oriented policy as its basic strategy of defense, and continues...

Constitution and the Basis of Defense Policy

Abstract In the face of unprecedented challenges of upcoming fossil fuel shortage and reliability and security of the grid, there is an increasing interest in adopting distributed, renewable, energy resources, such as microgrids (MGs), and engaging flexible electric loads in power system operations to potentially drive a paradigm shift in energy production and consumption patterns. Prior work on MG dispatch has leveraged decentralized technologies like combined heat and power (CHP) and heat pumps to promote efficiency and economic gains; however, the flexibility of demand has yet to be fully exploited in cooperation with the grid to offer added benefits and ancillary services. The object of the study is to develop microgrid optimal dispatch with demand response (MOD-DR), which fills in the gap by coordinating both the demand and supply sides in a renewable-integrated, storage-augmented, DR-enabled MG to achieve economically viable and system-wide resilient solutions. The key contrib...

Emerging from World War II, the youth of London found themselves in a period of traditional values, conformity and drabness. Struggling to escape the oppressiveness of morals, family obligations and strict discipline in schools and on the streets, a string of youth subcultures emerged as a way of rebellion and selfexpression, beginning with the Bohemians, and continuing today with punks and skin-heads. Somewhere in the middle lie the Mods, an immeasurably large and widespread cult of fashion-worshipping workingclass teens with money in their pockets and time on their hands.
