The rational allocation of corporate control between different behavioral agents has attracted more and more attention. This paper points out that scholars have studied the allocation of corporate control from the angles of the agency cost theory, property rights theory, corporate finance theory, and the theory of corporate governance, which has great value. However, the existing theories also have some flaws on the allocation of corporate control. First, people still have different understandings and views over the meaning of corporate control. Secondly, the existing research theoretically only observes and studies an arrangement of sheer level control, the allocation between final control and real control. This paper argues to build the two-tier allocation of corporate control： The first tier relation is between ultimate control rights and actual control rights, the second tier relation is between indirect control rights and direct control rights which are in actual control rights. This study can explain the resource allocation effects of corporate control, promote the development and improvement of the theory of the firm.展开更多

However, temperature-sensitive medical products may decay due to outside temperature changes. The time required to transport over the distance may vary a lot as well. As a result, the likelihood of the goods deteriorating is very high. There is a need for a study on cargo bay to prevent this and to protect the medical goods. In this paper, in order to protect the temperature sensitive medical goods, the inside cargo bay is equipped with the cooling fan device and the electric heating elements. These elements can be monitored and controlled according to the user’s discretion. By using the web server built inside the cloud server, the temperature can be controlled in real-time from anywhere without the limitation of distance. We built the proposed device, and installed it on the drone cargo bay. The test results show that the cargo bay can be temperature-controlled, and the setting can be maintained over a great distance. The user can watch the temperature variations during the transport and ascertain the goodness of the medical supply with the data. It is expected that such development can greatly enhance the utility of the drone operations, especially for the medical supply transport applications.展开更多

It also believes that when they are in homologous, the ownership of enterprise can be arranged in the best place. When the enterprise is under normal run, shareholders are its owner, but when it goes into bankruptcy, claimers should take place of shareholders becoming the owner of the enterprise. But in China, the ownership of state-owned enterprise （SEE） goes into double misplaces. Management controls the enterprise under the normal run, which leads salaries to seize the earnings and share equities. The state who acts as the shareholder not only lessens investments but also fixes its earnings as much as possible. It gives up the claim to residue, which leads claimers to bear the enterprise＇s residual risks （when the residual income is negative）. When the enterprise goes into bankruptcy, as the shareholder, the state determines whether it can exist or not in order to maximize its own utility. Rights of claimer are being seriously damaged as they can be manipulated freely in the enterprise. Banks＇ bad debts are also in an extremely high level. In this article, the author will establish a model and use the relative data to do technical analysis.展开更多

Nowadays power electronics research has added the importance of power quality studies, for concrete illustration, Custom Power Devices (CPD) and Flexible AC Transmission position (FACTS) devices. The approach offered in this paper utilizes the series and shunt compensator of Unified Power Quality Conditioner (UPQC) to inject a compensation voltage in-phase with the source current over voltage fluctuations. The execution of two structures of UPQC, left-shunt (L-UPQC) and right-shunt (R-UPQC) are investigated under diverse operating conditions based on the fuzzy logic controller to raise the value of power quality of a single feeder distribution system by MATLAB/Simulink programming. Various power quality issues have been analyzed in this study. Finally, the right shunt UPQC is outperformed in this proposed power system.展开更多

One such area involves data brokers, which have thus far gone unregulated. Data brokers use artificial intelligence to aggregate information into data profiles about individual Americans derived from consumer use of the internet and connected devices. Data profiles are then sold for profit. Government investigators use a legal loophole to purchase this data instead of obtaining a search warrant, which the Fourth Amendment would otherwise require. Consumers have lacked a reasonable means to fight or correct the information data brokers collect. Americans may not even be aware of the risks of data aggregation, which upends the test of reasonable expectations used in a search warrant analysis. Data aggregation should be controlled and regulated, which is the direction some privacy laws take. Legislatures must step forward to safeguard against shadowy data-profiling practices, whether abroad or at home. In the meantime, courts can modify their search warrant analysis by including data privacy principles.展开更多

As it is difficult to obtain the inverse of the right factor due to the high nonlinearity, the proving of the Bezout identity becomes troublesome. Therefore, two sufficient conditions are derived to manage this problem with the nonlinear feedback system as well as that with the uncertain nonlinear feedback system under the definition of Lipschitz norm.

The issues of authorization for geospacial DRM are concentrated on. To geospacial DRM, one aspect is the declaration and enforcement of access rights, based on geographic aspects. To the approbation of digital geographic content, it is important to adopt online access to geodata through a special data infrastructure （SDI）. This results in the interoperability requirements on three different levels： data model level, service level and access control level. The interaction between the data model and service level can be obtained by criterions of the open geospacial consortium （OGC）, and the interaction of the access control level may be reached by declaring and enforcing access restrictions in GeoAC. Then an archetype enforcement based on GeoAC is elucidated. As one aspect of performing usage rights, the execution of access restrictions as an extension to a regular SDI is illuminated.展开更多

This paper designs a model to show that： below a threshold level, with the increase of the cash-flow rights held by the controlling stockholder, the profit-diverting shares will probably go up, and the Tobin＇s Q of a listed company maybe go down; Only after that threshold point, does the profit-diverting share become a decreasing function of the cash-flow rights held by the controlling stockholder, and hence does Tobin＇s Q become an increasing function of the cash-flow rights held by the controlling stockholder.展开更多
