Shall We Have Universal Physical Education?
There are many arguments strongly in favor of it.
Is there any homemaker who regrets the passage of the Smtih-Hughes bill that has made possible the splendid work in home economics or who would abolish the good roads program now being carried out
Human vs. Computer Slot Car Racing using an Event and Frame-Based DAVIS Vision Sensor
This paper describes an open-source
implementation of an event-based dynamic and
active pixel vision sensor (DAVIS) for racing
human vs. computer on a slot car track. The
DAVIS is mounted in "eye-of-god" view. The
DAVIS image frames are only used for setup and
are subsequently turned off because they are not
needed. The dynamic vision sensor (DVS) events
are then used to track both the human and
computer controlled cars. The precise control of
throttle and braking afforded by the low latency of
the sensor output enables consistent outperformance
of human drivers at a laptop CPU
load of <3% and update rate of 666Hz. The sparse
output of the DVS event stream results in a data
rate that is about 1000 times smaller than from a
frame-based camera with the same resolution and
update rate. The scaled average lap speed of the
1/64 scale cars is about 450km/h which is twice as
fast as the fastest Formula 1 lap speed. A feedbackcontroller
mode allows competitive racing by
slowing the computer controlled car when it is
ahead of the human. In tests of human vs.
computer racing the computer still won more than
80% of the races.Unión Europea FP7-ICT-270324Unión Europea FP7-ICT-60095
The Change of Prevalence of Xerophthalmia on Lombok, September 1977 - September 1983
Berdasarkan data "Survei Prevalensi Kebutaan Gizi" tahun 1977, Lombok, Nusa Tenggara Barat, dinyatakan sebagai wilayah tinggi prevalensi xeroftalmia. Sebagai suatu wilayah dengan prevalensi xeroftalmia paling tinggi di Indonesia, banyak faktor risiko yang diidentifikasi bagi daerah ini, termasuk kejadian kecacingan, kekurangan frekuensi pemberian ASI pada anak yang masih menyusu; kekurangan "kamar cuci" di dalam rumah; variasi diet yang terbatas, tidak ada variasi konsumsi bahan pokok selain beras; dan kecilnya konsumsi sumber-sumber protein. Faktor risiko khusus xeroftalmi-korneal berkaitan dengan riwayat penyakit yang baru diderita si anak (campak dan infestasi berat kecacingan) dan kurang kalori protein berat. Sejak tahun 1978, Pemerintah Indonesia telah mengembangkan berbagai macam pendekatan untuk mengawasi (kontrol) xeroftalmia; sampai tahun 1982 telah mencapai 80% sasaran (anak Balita) dan telah menghasilkan penurunan prevalensi xeroftalmia di wilayah ini. Penurunan prevalensi ini dicapai tanpa penurunan secara proporsional faktor-faktor risiko terkait

Novel microsatellite control system
The authors are developing extremely simple yet quite capable analog pulse-coded neural networks for smaller-faster-cheaper spacecraft attitude and control systems. They will demonstrate a prototype microsatellite that uses the novel control system to autonomously stabilize itself in the ambient magnetic field and point itself at the brightest available light source
