We study the rendezvous problem in the asynchronous setting in the graph of infinite line following the model introduced in [13]. We formulate general lemmas about deterministic rendezvous algorithms in this setting which characterize the algorithms in which the agents have the shortest routes. We also improve rendezvous algorithms in the infinite line which formulated in [13]. Two agents have ...

Small papillary muscles about 2 mm long and 0.2 mm thick were dissected from the right ventricles of 16-19 day-old rats. Resting (between twitches) and active (at twitch peaks) striation patterns were photographed in living muscles using a light microscope. External muscle length was varied from Lmax, the length at which peak twitch tension was maximum, to 0.75Lmax, the length at which peak twi...

In this paper, we analyze approximation algorithms for two types of scheduling problems. The first is the n jobs scheduling problem with due dates on m identical machines to minimize the maximum lateness. For this problem n/m/I/Lmax, we propose two approximation algorithms and derive their worst case bounds. The second is the 2 x n flow shop scheduling problem with due dates to minimize the max...

The relationships between range of motion, optimal length for force production (lo), and passive force provide useful insights into the structure and function of muscles but are unknown for most individual muscles. We measured these values and examined their relationships in five strap-like muscles of the cat hind limb: caudofemoralis, semitendinosus, sartorius anterior, tenuissimus, and biceps...

We analyze a dual resource constrained (DRC) job shop in which both machines and workers are limited, and we seek to minimize Lmax, the maximum job lateness. An allocation of workers to machine groups is required to generate a schedule, and determining a schedule that minimizes Lmax is NP-hard. This chapter details a probabilistic method for evaluating the quality of a specific (but arbitrary) ...

it is accepted that noise pollution has a major impact on health, such as physical, physiological, psychological and performance related effects, all over the world. this study aims to evaluate noise pollution in four urban parks located in sanandaj city, iran and to zone it in gis environment. sound pressure level (spl) and maximum sound level (lmax) were measured at 45 points (each point was ...

Povzetek. V sestavku najprej vpeljemo komunikacijska omrežja in usmerjanje podatkov v njih, v nadaljevanju pa se osredotočimo na permutacijsko usmerjanje. Osrednji del sestavka je problem optimalnega permutacijskega usmerjanja na trikotniških mrežah. Predstavljen je optimalni permutacijski usmerjevalni algoritem, ki za usmerjanje vseh permutacij potrebuje lmax korakov, kjer je lmax najdaljša iz...

The discussion on the extension of existing airports and the construction of new ones has reached a new peak. This paper reviews the literature on the possibility of trading noise for number of aircraft operations in the context of increasing air travel. Moreover, two new laboratory studies are presented, which model two ways of immission reduction: (1) fading out old and loud aircraft at exist...

The influence of calcium concentration in the bathing solution on the force-velocity relations of the isolated, electrically excited cat papillary muscle was examined. Shortening velocity was directly measured at minimum loads by unloading or load clamping the muscle from the preload (at the length, Lmax, where maximum active tension was developed) to 0 (zero-load clamp), 2, 5, 10, and 15% of t...

The purpose of this study was to assess the relationship between psychological stresses and noise stresses on printery workers in Tehran, Iran. Hence, 267 workers were randomly selected. The Leq and Lmax were measured and the psychological stresses such as depression, anxiety, aggression and job satisfaction were also studied by the relevant questionnaires. The data were statistically analyzed ...
