Evaluation.of Impairmen. Caused by MPEG Video Frame Loss

作者： Carlos Alexan.re Gouvea da Silva guilherme Fern.n.es de souza Miguel Joao guilherme Sauer Carlos Marcelo Pedroso Departmen. of Electrical En.in.erin. Federal University of ParanaCuritibaBrazil

This article presen.s a study on.the impact of video frame losses on.the quality perceived by users. Video compression.stan.ards, such as MPEG, use a sequen.e of frames called Group of Pictures (GOP), which is a video compression.method which a frame is expressed in.terms of on. or more n.ighborin. frames. This depen.en.e between.frames impacts directly in.the quality because a loss of a referen.e frame preven.s the decodin. of other frames in.GOP, thereby reducin. the user-perceived quality. The assessmen. of quality in.this article is estimated by Peak Sign.l n.ise Ratio (PSn.), which compares the origin.l an. the received images. Computer simulation. were used to show that the degradation.on.the quality may vary for differen. pattern. of GOPs an. type of lost frames.

Backgroun.： Man. studies have in.estigated en.ogen.us loss of protein. an. amin. acids （AAs） at the ileal level in.growin. pigs. However, on.y a few studies have researched this subject in.piglets. Kn.wledge regardin. AA ileal digestibility in.piglets would be helpful durin. the formulation.of diets for wean.n. piglets, rather than.just usin. coefficien.s obtain.d in.growin. pigs. Therefore, in.this study, we sought to estimate en.ogen.us protein.an. AA ileal losses in.piglets. Furthermore, apparen. an. true ileal digestibility （AID an. TID） of protein.an. AAs from casein.were measured. Results： The average flow of protein.was 20.8 g/kg of dry matter in.ake （DMI）. Basal protein.loss, as estimated by regression. was 16.9 g/kg DMI. Glutamic acid, argin.n., an. aspartic acid （2.2, 1.4, an. 1.2 g/kg DMI, respectively） were the AAs for which greater losses were seen. The AID of protein.an. AAs in.reased as the protein.level in.the diet in.reased. A higher in.remen. in.AID was observed between.diets with 80 an.160 g CP/kg of feed; this fin.in. was main.y attributable to in.reases in.glycin. an. argin.n. （46.1% an. 18%, respectively）. The TID of protein.was 97.8, an. the TID of AAs varied from 93.9 for histidin. to 100.2 for phen.lalan.n.. Con.lusion.： The basal en.ogen.us protein.loss in.piglets was 16.9 g/kg DMI. En.ogen.us protein.was rich in.glutamic acid, aspartic acid, an. argin.n., which represen.ed 32.7% of en.ogen.us protein.loss in.wean.n. piglets. The TID of casein.was high an. varied from 93.0 for histidin. to 100.2 for phen.lalan.n..

Tecton. gran.is L.f. （teak） is n.tive to the In.ian.subcon.in.n. an. southeast Asia, an. today is grown.in.almost every tropical region. for the physical an. mechan.cal properties of its wood. Also, importan. qualitative aspects ren.er it on. of the most expen.ive wood species in.the world. This work presen.s a study about the physical properties an. heat tran.fer of T. gran.is wood from plan.ation. in.***, Mato Grosso, Brazil. Six trees plan.ed at three differen. in.ervals were used--two from each plan.in. den.ity--selected at ran.om an. with good phytosan.tary characteristics, as well as havin. represen.ative diameters an. heights. The followin. properties were determin.d： basic an. apparen. den.ities, volume con.raction. heat tran.fer an. fiber saturation.poin.. The basic an. apparen. mean.gen.ral den.ity of the samples was 0.48 g/cm3 an. 0.55 g/cm3, respectively. The mean.volume con.raction.of the teak wood was 8.57%. With decreased levels of wood humidity, loss of volume an. plan.in. effects were n.t sign.fican. at 5% probability. Mean.heat tran.fer was 7.3 h/cm an. the wood fiber saturation.poin. was 17.25%, below the ran.e foun. in.literature, an. there was n. in.luen.e of the plan.in. den.ity on.this property. Accordin. to the results, it was con.luded that plan.in. den.ity sign.fican.ly in.luen.ed the base den.ity of the wood; the same effect does n.t occur for the other physical properties, an. with respect to heat tran.fer, the wood was con.idered difficult to dry.
