Synthesis of N‐(α‐Alkoxyalkyl)benzotriazoles Catalyzed by Acidic Ionic Liquid at Room Temperature
Authors: Wang Hong‐Xia , Ji Shun‐Jun , Gu Da‐Gong 
Published: July 2007

AbstractN‐(α‐Alkoxyalkyl)benzotriazoles were synthesized via the condensation of benzotriazole with various aldehydes and alcohols catalyzed by acidic ionic liquid [hmim]HSO4 at room temperature. The yield was up to 99%. This novel method was effective when triethoxymethane was utilized instead of alcohols. Moreover, acidic ionic liquid could be reused easily with no significant degradation of its catalytic activity.

Authors: Wang Li‐Qiong , Liu Yan‐Hong , Zhang Jian‐Guo , Zhang Tong‐Lai , Yang Li , Qiao Xiao‐Jing , Hu Xiao‐Chun , Guo Jin‐Yu 
Published: July 2007

AbstractIn this paper, the synthesis, crystal culturing and single‐crystal X‐ray crystallography of 1,3‐di(2‐p‐tolylvingl)‐ 2,4,6‐trinitrobenzene (DTTB) were reported. FT‐IR, 1H NMR and mass spectroscopy techniques were employed to characterize this compound. The results show that this single crystal belongs to triclinic system with space group P‐1. Density functional theory (DFT) B3LYP was employed to optimize structure and calculate frequencies of the title compound. The calculated geometrical parameters were close to the corresponding experiment ones. The thermal decomposition of DTTB was investigated by DSC and TG‐DTG methods at the heating rate of 10 °C/min. It was observed that the initial decomposing temperature of DTTB was higher than that of TNTM, although its melting point was lower than that of TNTM, indicating that DTTB has higher heat resistant ability.
Consumers’ perceptions of direct marketing techniques
Authors: Brezen Tamara S. , Block Martin P. , Schultz Don E. 
Published: July 2007

Direct marketing has become a highly popular and successful component of marketing. Today direct marketing-originated sales are growing at more than twice the rate of all general merchandise sales. This growth signifies an important shift in the marketing efforts of many companies to more selectively and directly target their customers with less waste and more timely response. Despite this growth, the research literature on direct marketing is lacking in both its breadth of coverage across the various techniques available and in its depth of investigation in any one area. For instance, most studies have narrowly focused on through-the-mail techniques such as direct mail or catalog shopping. One obvious reason for this emphasis is the ability on the part of the researcher to control for message exposure and contain research costs. Direct marketing generally encompasses much more, however, such as direct response advertising scheduled in the customary mass media channels — radio, television, newspaper, and magazine — as well as telemarketing and door-to-door selling. The available research has also been developed primarily to define the demographic and psychographic characteristics of the direct marketing consumer, or to quantify the sales/inquiry response of alternative executions controlled experimentally in the field. Virtually no published research has addressed how the consumer, rather than the researcher or practitioner, perceives direct marketing; yet, insight into the way the consumer views direct marketing in its various forms, and how the consumer sees him/herself in relation to these techniques, is vitally important to the direct marketer.
Why recipients of direct mail do and don't respond
Authors: Gould James S. 
Published: July 2007

Annually, billions of dollars are spent on direct mailings. Of these monies spent, an estimated 60 to 90 percent is wasted because recipients either did not read the mailing or did not respond to the offer. From the recipients’ perspective, much of the direct mail received is unwelcomed and referred to as “junk mail”. This study examines recipient perceptions of direct mailings received and differentiates between the wanted, unwanted, responded to and not responded to categories. Marketers using direct mail in their advertising-promotion mix will discover the findings to be helpful for developing mailings which are preferred by recipients and more likely to obtain responses. The initial study may also inspire researchers to further extend these avenues of exploration.
A profile of direct marketing television shoppers
Authors: Lincoln James E. , Cunningham Isabella C.M. 
Published: July 2007

The researchers used a national mail survey to gather data on the motivational, attitudinal, psychographic, and socioenvironmental characteristics of consumers. Stepwise discriminant analyses of 886 usable responses revealed that significant differences between direct marketing television shoppers and non-shoppers could be attributed to ten variables. The two groups differed in their need for affiliation, need for convenience, and attitude toward risk. Other significant discriminators were: sex, race, age, the absence of children in the home, late night television viewing, and social isolation. The latter two variables helped provide support for two hitherto untested industry notions — the “theory of sales resistance,” and the “isolation hypothesis”. Identifiable differences were used to help the researchers develop a profile of direct marketing television shoppers.
Increasing response rates using an inducement question in mail surveys
Authors: Geurts Michael , O‘Neill Michael F. , Albaum Gerald , Lawrence Kenneth 
Published: July 2007

The authors report on a technique that has been used successfully to increase response rates. The technique is to include in the questionnaire an initial question, called an inducement question, whose intent is to arouse the respondents’ thoughts and feelings. This paper explores the problems associated with using an inducement question and reports two studies in which the technique substantially increased the response rate. The initial idea for an inducement question occurred in response to a marketing researcher from Green Mountain Power of Vermont asking one of the authors if there were ways that the nonresponse to a survey of stockholders could be reduced. The response rate in previous surveys of stockholders had generally been quite low. It appeared that the stockholders were indifferent and apathetic about past surveys. It was suggested to the researcher that if the initial question of the survey was: “Management at Green Mountain has recently decided to abandon the payment of dividends. Do you favor this policy?,” the response rate would increase substantially.
Compliance strategies in direct response advertising
Authors: LeBourveau Carol A. , Robert Dwyer F. , Kernan Jerome B. 
Published: July 2007

Rising personal selling costs, market demassification, and pressures for advertising accountability are often-mentioned forces accounting for the recent surge of interest in direct marketing. Dollar-wise, direct marketing is credited with billions in media expenditures and over a hundred billion in sales. Meanwhile, the state of theory concerning buyer or seller behaviors in this field is a notch above folklore. This study develops a working definition of direct marketing, which supports a benchmark measurement of its prevalence in magazine advertising. Cialdini's taxonomy of communication strategies is used to content analyze a sample of magazine advertisements. Results indicate that while both conventional display ads and direct response ads rely mostly on friendship/liking strategies, direct response ads use a scarcity theme significantly more than do conventional ads. Moreover, direct response ads support their principal themes with implicit reciprocation in approximately 33 percent of the cases.
How many names should we test?
Authors: Croy Calvin D. 
Published: July 2007

This article illustrates how to determine the number of names to test mail in order to infer whether the rollout response rate will likely exceed some desired level. Also shown is how to predict the likely response rate of a full panel after a test mailing. The article is aimed at direct marketers with little statistical background. Two example calculations are provided in detail: one for determining sample size and one for determining confidence intervals. Throughout the text, emphasis is placed on presenting, in a readable fashion, the statistical rationales that underlie all formulae. The sensitivity of the sample size formula is also explored.
A design consideration of deflection‐modulated EBS amplifier diodes
Authors: Makishima Hideo , Mitomi Osamu , Ishitsuka Fuminori 
Published: July 2007

AbstractIt is expected that the deflection‐modulated EBS amplifier can be used in the microwave band up to quasi‐millimeter wave band as a power amplifier, in which the diode is an important integral part. This paper will present a diode design method suitable for high frequency. First, the electron pair profile, generated in the diode by electron beam illumination, will be found using the Monte Carlo method, and its distribution will be obtained as a function of metal thickness and material, as well as the p+ layer thickness. The amplitude response of the output current due to carrier transittime in the depletion layer can then be found from the profile. This permits us to propose an amplifier design method, by which the diode design parameters for maximum diode efficiency can be found. Based on the design concept presented in this paper, we design a 10‐GHz Si‐pn diode and GaAs Schottky diode. The design parameter effects on characteristics are given, and Si or GaAs EBS diode performance and limitations are clarified.
Radiation characteristics of ring antennas for electron plasma waves
Authors: Egashira Shigeru , Morita Yuzuru , Yoshida Yoshinori 
Published: July 2007

AbstractA theoretical analysis and experiments on one‐ and two‐element ring antennas in an isotropic compressible plasma are repeated. First, a two‐element ring antenna connected to the inner and outer conductors of a coaxial feeder is analyzed by decomposing the system into a zero phase type and a positive phase type. The analysis uses Fourier series expansion. Numerical results reveal that in both one‐ and two‐element systems the current is approximated by a triangular distribution, i.e., a charge with a uniform distribution, if the ring diameter is much smaller than the free space wavelength. In the case of two‐element systems, the charge distributions of elements #1 and #2 are out of phase. The input impedance of the two‐element ring is much smaller than that of the one‐element system. The measured and calculated radiation patterns of a one‐element ring for the electron plasma wave agree well except near θ = 90°. The side‐lobe level of the two‐element ring is much lower than that of the one‐element ring and the radiation characteristics are much improved. It is theoretically and experimentally confirmed that the radiation efficiency of the two‐element ring is much better than that of the one‐element ring for electron plasma waves.
Passive realization of nonlinear networks. Existence of C1 internal energy functions
Authors: Takahashi Haruhisa , Kumagai Sadatoshi , Kodama Shinzo 
Published: July 2007

AbstractThe problem of determining the class of passive nonlinear networks with the C1 internal energy function proposed by Wyatt, Chua et al., is closely related to the passive realization of nonlinear networks. This paper considers the positive‐real lemma which plays a fundamental role in the passive realization of linear networks. Here, the lemma is extended to general nonlinear networks using the property of solution in the optimal control problem. the results obtained provide an answer to the problem proposed by Wyatt, Chua et al. the positive‐real lemma for the linear case can easily be derived as a special case of the general nonlinear case. the realization problem for the nonlinear n‐port is formulated, and a fundamental property for the passive realization is shown as an extension of the linear case.
A method of coding for narrow‐band CPFSK
Authors: Yamada Takahiro , Harashima Hiroshi , Miyakawa Hiroshi 
Published: July 2007

AbstractAlthough the continuous phase FSK (CPFSK) scheme has been used for narrow‐band data transmission, its error rate performance is rather poor. This paper describes a coding method for improving the error rate performance of the narrow‐band CPFSK scheme with modulation indices of 1/3 and 1/4. the proposed method examines the structure of the signal space for the given modulation scheme and avoids using the signal metric of small value in the coding. Hence, the objective of this method is not error correction, but maximization of the minimum signal metric. the application of this method in narrow‐band CPFSK system yields better performance than the MSK scheme in terms of both bandwidth and error rate.
Modified three‐dimensional self‐complementary array antenna over a finite ground plane
Authors: Kasahara Takeshi , Sawaya Kunio , Mushiake Yasuto 
Published: July 2007

AbstractA balanced wideband antenna based on the self‐complementary principle is known as a log‐periodic antenna. Another type of self‐complementary antenna, the unbalanced type, has not been extensively studied, even though it is useful in many areas, including mobile communication. This paper describes an unbalanced wideband antenna with an extremely simple structure based on the principle of the three‐dimensional self‐complementary antenna. A method for deriving a unidirectional and constant‐impedance antenna from a three‐dimensional self‐complementary antenna having several symmetrical radiation lobes is proposed, and a theoretical and experimental analysis of the radiation characteristics of a monopole‐slot pair with a finite ground plane is given. It is shown that the radiation characteristics remain almost unchanged when the ground plane is larger than one wavelength in four directions from the center of the antenna pair. It is also shown that the gain in the maximum radiation direction of an element pair is much higher on a semi‐infinite ground plane than on an infinite ground plane. A wide‐band antenna consisting of element‐pairs spaced at equal intervals and with a length taper is described. the antenna exhibits a substantial array effect on the gain. the gain is higher than that of a monopole‐notch array antenna with a ground plane.
A proposal of time division switching network using variable time slot multi/demultiplexing circuit
Authors: Yasui Tadahiko , Takahashi Tatsuro 
Published: July 2007

AbstractThis paper presents a time division switching network in which only functionally expanded multiplexing switches are connected in cascades. It has been designated Variable Multi‐demultiplexing Time Division Switching Network (VTDS). Input multiplicity is commonly one in the conventional multiplexing switch (switching circuit element); however, the one proposed herein accommodates lines whose multiplicity is more than one. All VTDS holding memories, which store the correspondence between input timeslots and output timeslots, can be realized with the same economical low‐speed memories. Moreover, the switching network structure is optimized assuming that gate cost is proportional to gate speed. the optimum VTDS switch size gradually decreases towards the center stage. an outstanding VTDS feature is that multiplexing switching gate speed can be utilized most effectively because VTDS needs no time memory and speech path network construction is freed from random access memory speed limit. Other VTDS features: (1) input multiplicity is one; (2) channel graph is serial‐parallel type; and (3) it eliminates highway (space) switches.
Graph theoretical approach to a highly reliable network
Authors: Imase Makoto , Okada Keiji , Ichikawa Haruhisa 
Published: July 2007

AbstractThis paper presents a method of constructing a highly reliable and efficient communication network using two types of directed graphs called “extended complete graph (ECG)” and “quasi‐ECG.” They are nearly minimum in diameter and nearly maximum in connectivity for any number of nodes. These graphs are evaluated for diameter, connectivity and “vulnerability” which is defined to represent the throughput deterioration caused by network constituent failure. A network constructed using (quasi‐) ECGs is also shown to be comparative to the commercial network in the mean value of transit switching stages per call.
