SideChannel-3D: Acoustic, Vibration, Magnetic, and Power Side-Channel 3D Printer Dataset

This dataset contains multimodal sensor data collected from side-channels while printing several types of objects on an Ultimaker 3 3D printer. Our related research paper titled "Sabotage Attack Detection for Additive Manufacturing Systems" can be found here: https://doi.org/10.1109/ACCESS.2020.2971947. In our work, we demonstrate that this sensor data can be used with machine learning algorithms to detect sabotage attacks on the 3D printer.

Perfect and Related Codes

This dataset is devoted to 1-perfect codes. Currently, it is mainly focused on the concatenated ternary perfect codes, but there is also an additional content, see (3) below, (1-2) This dataset contains all inequivalent concatenated ternary 1-perfect codes of length 13. Additionally, it contains some components necessary to obtain such concatenated codes, namely, collections of disjoint ternary distance-3 Reed-Muller-like codes of length 9, see p.(1) below.

Instructions:

(1) Each text file in the dataset archived in H93.zip keeps collections of disjoint $(9,3^6,3)_3$ codes, coded in the following manner (the file names are coded with equivalence classes of the corresponding codes, from 0 to 3; some files are empty, for example, "n00123", because two codes from equivalence class 0, one code from class 1, one code from class 2, and one code from class 3 cannot be packed in a disjoint manner). Each line corresponds to one representative of such a collection. If the number of codes is M, then the line contains M records like "N T PPPPPPPPP". "N" denotes the number of a code in the list 7codes.py of seven permutably inequivalent codes (note that "permutably equivalent" is not the same as "equivalent"; only first 4 are inequivalent in the sense of $Aut(H(9,3))$, the last 3 are equivaleng to the code number 3). "T" is the number of a translation vector in the list 0: 000000000, 1: 120000000, 2: 102000000, 3: 100200000, 4: 100020000, 5: 100002000, 6: 100000200, 7: 100000020, 8: 100000002, and "PPPPPPPPP" is a coordinate permutation. To reconstruct the corresponding code, one should take the code number "N" from 7codes.py, apply the coordinate permutation "PPPPPPPPP" in the following manner: $$(x_0,x_1,x_2,x_3,x_4,x_5,x_6,x_7,x_8) \to (x_{P^{-1}(0)},x_{P^{-1}(1)},x_{P^{-1}(2)},x_{P^{-1}(3)},x_{P^{-1}(4)},x_{P^{-1}(5)},x_{P^{-1}(6)},x_{P^{-1}(7)},x_{P^{-1}(8)}),$$ and add the translation vector number "T" to all codewords.  After M records about the codes, each line contains: (ii) the record "-A", where A is the order of the automorphism group of the collection of codes; (iii) the record "+R", where 6+R is the rank of the collection, that is, the dimension of the union of the (non-translated) codes (the minimum rank is 6 and the maximum is 8=9-1 because of the all-parity check, so R is 0, 1, ro 2); (iv) the record "~" or "|", where "~" means that the collection can be continued to a collection of M+1 codes and "|" means that no $(9,3^6,3)_3$ code (satisfying the all-parity check) can be added to the complement (this can only happen when M is 6 or 9).

(2) The file "concat13" (arxived to concat13.xz; the original file is 1.7GiB) contains the list of all inequivalent concatenated ternary 1-perfect codes of length 13 in the following form. Each length-9 partition in the form described in p.(1) (the order of records is (i), (iii), (ii), and the last record contains generators of the group of permutations of 9 codes induced by the automorphism group of the partition) is followed by the list of concatenated codes obtained with this partitions. The records for each code are the following:

(i) "A" or "B" indicate the partition of $H(4,3)$ into 1-perfect codes.

(ii) The next 8 numbers show the permutation $p$ of the codes of the partition.

(iii) The record "+R" means that the rank of the code is 10+R (10, 11, or 12).

(iv) The record ":K" means that the dimension of the kernel of the code is K (the kernel is the set of all periods of the code, that is, the translations that send the code to itself).

(v) The record "/S" means that the code can be represented as a concatenated code in S different ways (partitions 9+4 of coordinates); for the rank-10 Hamming code this number is 13; for rank-12 codes it is 1; for rank-11 codes it is from 1 to 4.

(vi) The record "-A*K" means that the order of the automorphism group of the code is A*K, while A is the number of authomorphisms that keep the coordinate partition 9+4, i.e., the current concatenation structure (if (iv) is "/1", then K necessarily equals 1).

If the record (v) is "/1" or "/13", then there are no more records, because this guarantees that an equivalent code cannot be obtained by concatenation in another way (in particular, from a different partition).

If the record (v) is "/2", "/3", or "/4", then such codes were checked for isomorphism, and one more record is given:

(vii) This record contains a symbol "n" or "o" and some number. "n" means that the code is new, and it is not equivalent to any of the codes above, and the following number is its unique number (among the codes with symbol "n" in the record). "o" means that the code is not new and it is equivalent to one of the codes above, namely, the one with symbol "n" followed by the same number.

So (ATTENTION!!!), some lines of the database correspond to equivalent codes; to read only inequivalent codes, one should ignore the lines with symbol "o".

Additional material: (3) The file all_hamming15.zip contains the database file (to reduce the size, the xz-compression was applied) with 64864800 check matrices of [15,11,3] different Hamming codes, the database file with the 232 inequivalent pairs of disjoint Hamming codes, the file readme.txt with instructions and some scripts.

Automation ROI - Industry Data from Bengaluru, India

Software Industry has adopted automated testing widely. The most common method is the automated GUI tests for the functional scenarios to reduce manual testing and increase the repeatability. The idea of reducing execution time for quality provides a rational for the executive management to allocate funds to adopt automation and invest in the setup including people, process, tools to achieve  faster time to market. There are variety of practices like frameworks, tools, methods, procedures, models, technologies that are engaged to achieve automation.

DTU three-channel room impulse response dataset for direction of arrival estimation 2020

The data set contains 152 measurements of room impulse responses for direction of arrival estimation, using a compact three-channel microphone array. Sources are placed at 10-degree intervals from -90 to 90 degrees in the azimuth plane at range 150 cm. There are also 5 off-grid measurement positions and 6 off-range positions - at ranges 1 m, 2 m, 2.5 m and 3 m. The measurements are performed in a furnished classroom, which is approximately rectangular and of dimensions 9 x 6 x 3 m. The reverberation time is 0.4 s.

Instructions:

The data set contains: ·     Data: Room impulse responses are included in the file “RIRs_DTU.mat”·     Images: Pictures of the room and setup, included as *.jpg files.·     Documentation: A pdf file that contains the relevant info regarding the dataset.
