|
 | short laser pulses were used for generating surface acoustic waves (saws) on optically opaque solids via the thermoelastic effect. the spatial and temporal shapes of the laser pulses were either a spot or a line of variable total width delta = 2alpha with a gaussian power distribution. maximal efficiency is obtained when alpha = nu(sub r)tau(nu(sub r): rayleigh velocity, 2 tau: total laser-pulse length). this condition is caused by interference ... |

| Recent Trends in Palestinian Terrorism. II |

B. Hoffman; RAND CORP SANTA MONICA CA
|
| It is generally believed that, in the aftermath of Israel's invasion of Lebanon in June 1982, there has been an appreciable decline in Palestinian terrorist activity. However, a statistical examination of data in the Rand Corporation's Chronology of International Terrorism presents a rather different and considerably less sanguine picture. First, there was little change in the total level of Palestinian terrorism against Israeli targets when measured over six month intervals ... |

| The Prevention of Terrorism and Rehabilitation of Terrorists: Some Preliminary Thoughts |
FEB 85 |

| Authors:
B. Hoffman; RAND CORP SANTA MONICA CA
|
| Despite many other disagreements among experts on terrorism, it is at least agreed that individuals who become terrorists feel alienated from society. This alienation may be the product of distinct social, economic, political, or psychological factors or a combination of them. The person who drifts into terrorism, then, feels himself to be an outsider. His self-perception as an outsider may be based on his ethnic or religious affiliation, his inability ... |

| Right-Wing Terrorism in Europe Since 1980 |

| Authors:
B. Hoffman; RAND CORP SANTA MONICA CA
|
| Although there has been a general decline in neo-Nazi/neo-fascist terrorism since the 1980 bombings, the threat posed by right-wing extremists in Germany, France and, to a lesser extent, Italy, has not subsided. Each of these countries has a tradition of right-wing militancy, political and racial intolerance, and violence. Events involving the neo-Nazis and neo-fascists have already demonstrated that where hatred and intolerance exist, the potential for violence and terrorism exists ... |

| The Siege Mentality in Beirut: An Historical Analogy between the British in Palestine and the Americans in Lebanon |
JAN 1984 |
|
| Authors:
B. Hoffman; RAND CORP SANTA MONICA CA
|
| The problem confronting the U.S. Marines presently stationed in Lebanon is similar to the one which the British Army faced in Palestine more than thirty years ago. In 1947, British troops, like their later day Marine counterparts, were deployed in urban areas where they were subjected to hit-and- run attacks by a determined and anonymous (though not, as is the case in Lebanon, suicidal), adversary. The British attempted to prevent ... |

| This eighth quarterly reports accomplishments during the period 15 December 1963 to 15 March 1964 on a theoretical and applied research program directed toward prolonging the lifetime of magnetohydrodynamic (MHD) energy converters to the range 1000 K to 2000 K. The process of interest is the use of the self-induced electric field in the MHD generator for electricaj breakdown of appropriate working fluids of interest. Work at present is directed ... |

|
| A theoretical and applied research program directed toward prolonging the lifetime of magnetohydrodynamic (MHD) energy converters to the range 1000 K to 2000 K is reported. The process of interest is the use of the self-induced electric field in MHD generator for electrical breakdown of appropriate working fluids of interest. Work is directed toward the use of potassium for Rankine (Vapor) cycles. The potassium vapor blowdown system reached operational capability. ... |

| Authors:
B. Hoffman; F. H. Shair; GENERAL ELECTRIC CO PHILADELPHIA PA MISSILE AND SPACE DIV
|
| This report describes a theoretical and applied research program directed toward prolonging the lifetime of magnetohydrodynamic (MHD) energy converters by reducing the necessary operating temperatures to the range 1000 - 2000 K. The process of interest is the use of the magnetically induced electric field in the MHD generator for electrical breakdown of appropriate working fluids. Work was directed toward the use of alkali metals for Rankine (vapor) cycles (although ... |

| Report on Nondestructive Testing Activities at Research and Development Group, |
28 AUG 1961 |
|
| Authors:
B. Hoffman
|
| A summary is given of nondestructive test research and development activities which have resulted in the development of new equipment, techniques and applications employing electro-magnetic and ultrasonic principles. A prototype ultrasonic tire test system is described which automatically scans a tire tread area for the presence of flaws while simultaneously recording results obtained. (Author, modified). |
