The aim of this in.estigation.was to defin. the effectiven.ss of n.n.con.act dryin. usin. ultrason.c vibration.. Disk radiators were used for carryin. out experimen.s, an. a special dryin. chamber was design.d to provide reson.n. amplification.of ultrason.c vibration. (from 130 to 150 dB). Dryin. of gin.en. an. other vegetables demon.trated that the application.of ultrason.c vibration. reduced power in.uts by 20% in.comparison.with con.ective dryin.. It also led to a decrease of 6% in.fin.l moisture con.en., if the duration.of dryin. was con.tan.. The level of in.en.ification.of ultrason.c dryin. was high (up to 50 g for 1 kg of dryin. material), which helped to lower the temperature of the dryin. agen. an. improve the quality of the dried products.

Thin.organ.c films fin. expan.in. application. in.electron.c an. optoelectron.c devices, biotechn.logy,food packin., an. for man. other purposes. Amon. other factors, the stability of films with a thickn.ss below a micrometer is determin.d by the zero-poin. an. thermal fluctuation. of the electromagn.tic field. These fluctuation. result in.the van.der Waals an. Casimir free en.rgy an. forces between.a film an. a substrate. The fluctuation.n.uced force may be both attractive an. repulsive makin. the film either more or less stable, respectively. Here, we review recen.ly obtain.d results for the Casimir free en.rgy of both freestan.in. an. deposited on.the metallic an. dielectric substrates peptide films. We also perform computation. for the free en.rgy of the peptide films deposited on.a silica glass substrate in.the region.of parameters where this free en.rgy van.shes. Possible application. of the obtain.d results are discussed.

The adsorption.an. electron.c properties of isolated cobalt phthalocyan.n. （CoPc） molecule on.an.ultrathin.layer of n.C1 have been.in.estigated. High-resolution.STM images give a detailed picture of the lowest un.ccupied molecular orbital （LUMO） of an.isolated CoPc. It is shown.that the n.C1 ultrathin.layer efficien.ly decouples the in.eraction.of the molecules from the un.ern.ath metal substrate, which makes it an.ideal substrate for studyin. the properties of sin.le molecules. Moreover, stron. depen.en.e of the appearan.e of the molecules on.the sample bias in.the region.of relatively high bias （〉 3.1 V） is ascribed to the image poten.ial states （IPSs） of n.CI/Cu（100）, which may provide us with a possible method to fabricate quan.um storage devices.

This paper is devoted to bin.ry stars belon.in. to the class of eclipsin.-variable *** an. spectroscopic an.lysis of eclipses allows us to determin. geometric parameters of the orbit an. physical characteristics of stellar compon.n.s as well as in.lin.tion. of stellar equators to the orbital plan.. Estimation. of in.lin.tion. can.be obtain.d from measuremen. of the Rossiter-McLaughlin.effect, which is discussed usin. examples of some eccen.ric bin.ries with an.an.malous apsidal effect. Our task is to fin. the complete spectrum of solution. of the equation.of apsidal motion. depen.in. on.the in.lin.tion. of the polar axes of the compon.n.s to the orbital on. for these systems, based on.their in.ividual spectroscopic an. photometric observation.l data. The matrix of solution. allows us to select those pairs of polar in.lin.tion. that provide agreemen. with the observation.l apsidal period.

The paper proposes a solution.to the problem classification.by calculatin. the sequen.e of matrices of feature in.ices that approximate in.arian.s of the data matrix. Here the feature in.ex is the in.ex of in.erval for feature values, an. the n.mber of in.ervals is a parameter. Objects with the equal in.ices form gran.les, in.ludin. in.ormation.gran.les, which correspon. to the objects of the train.n. sample of a certain.class. From the ratios of the in.ormation.gran.les len.ths, we obtain.the frequen.y in.ervals of an. feature that are the same for the appropriate objects of the con.rol sample. Then. for an.arbitrary object, we fin. object probability estimation.in.each class an. then.the class of object that correspon.s to the maximum probability. For a sequen.e of the parameter values, we fin. a con.ergin. sequen.e of error rates. An.addition.l effect is created by the parameters aimed at in.reasin. the data variety an. compressin. rare data. The high accuracy an. stability of the results obtain.d usin. this method have been.con.irmed for n.n. data set from the UCI repository. The proposed method has obvious advan.ages over existin. on.s due to the algorithm’s simplicity an. un.versality, as well as the accuracy of the solution..

The presen. paper solves the train.n. problem that comprises the in.tial phases of the classification.problem usin. the data matrix in.arian. method. The method is reduced to an.approximate “slicin.” of the in.ormation.con.ain.d in.the problem, which leads to its structurin.. Accordin. to this method, the values of each feature are divided in.o an.equal n.mber of in.ervals, an. lists of objects fallin. in.o these in.ervals are con.tructed. Objects are iden.ified by a set of n.mbers of in.ervals, i.e., in.ices, for each feature. Assumin. that the feature values within.an. in.erval are approximately the same, we calculate frequen.y features for objects of differen. classes that are equal to the frequen.ies of the correspon.in. in.ices. These features allow us to determin. the frequen.y of an. object class as the sum of the frequen.ies of the in.ices. For an. n.mber of in.ervals, the maximum frequen.y correspon.s to a class object. If the features do n.t con.ain.repeated values, the error rate of train.n. ten.s to zero for an.in.in.te n.mber of in.ervals. If this con.ition.is n.t fulfilled, a prelimin.ry ran.omization.of the features should be carried out.
